some of the features of the N9310A and N9320B and illustrates how easy it is to use this
equipment to make measurements. Until now, you would have to buy a more expensive
signal generator to get the features provided by the N9310A. With the N9310A you can generate
RF signals from 9 kHz to 3 GHz, an output exact amplitude ranging from -127 dBm to 13
dBm. The SSB phase noise is better than -95 dBc per hertz, at 20 kHz offset, and the minimum
switching time is less than 10 milliseconds. What does that mean to you? It meets more
specification margins to make your testing more accurate. The N9310A supports amplitude, frequency,
phase and pulse modulation, along with swept signal output, plus there’s an option that
provides additional internal IQ modulation for generating digital signals. For price-sensitive budgets, the N9320B delivers
unparalleled functionality. It offers best in class performance for a wide range of applications.
The N9320B supports 9 kHz to 3 GHz frequency range. The preamplifier option displays low
display average noise level, which means lower signals can be detected. Better than plus
10 dBm third-order inner modulation means better dynamic range performance and impressive
sweep speed. Its standard features include a one-button
PowerSuite and a power meter function. The tracking generator provides you with a cost-saving
means of measuring the frequency response characters without the need for a more expensive
network analyzer. The N9320B also supports AM, FM, ASK and FSK demodulation analysis.
Both the N9310A and the N9320B feature a highly evolved user-friendly interface with a 6 ½
inch color display screen, 11-language display and USB interfaces in front and rear panels.
Easy to use PC software is provided to help set up a remote operation environment between
controller, computer, and your N9320B using the USB LAM GPIB interface. Quite simply, all of that make the N9310A
and the N9320B easy to operate. The optional RF training kit used with the N9310A and N9320B
provides basic RF instructional labs. It is a great option for universities and colleges.

N9310A low-cost signal generator and N9320B spectrum analyzer can be in meeting your measurement
requirements. Thank you for joining us. General purpose operation of the N9310A and
N9320B is simple. Here is a quick demo on how to generate a continuous wave with the
N9310A and display the signal on the N9320B. To generate a 700 MHz / -20 dBm continuous
wave signal select a frequency and amplitude parameters and enable the RF output. The auto
tune key allows you to quickly find the highest level signal across the bandwidth and center
the signal on the screen. This feature enhances accuracy in measurement speed. If you want
to measure a low level, for example a -110 dBm signal, the N9320B option preamplifier
is helpful. It improves the instrument’s sensitivity to detect lower level signals
such as spurs and harmonics. Set the frequency, span, reference level,
and attenuation as shown. RBW in the resulting screen, it is still hard to see the signal
clearly. To address this, when you enable the preamplifier the noise floor decreases
and the low-level signal is then easily detected. The N9310A generates sweep signals in step
or list mode. Step sweep allows you to enter RF output start and stop frequencies and amplitudes,
a number of equally-spaced steps to dwell upon and the amount of dwell time at each
point. This sweep helps you generate a series of CW signals with specific frequency and
amplitude you entered. This demonstration shows how easy it is to general step swept
type signals. First enter the sweep sub-menu. Then set the
start and stop frequency and sweep output amplitude. Finally, set the dwell time at
each point and activate the RF output. Now you have the 2 MHz step signals from 960 to
980 MHz with -20 dBm amplitude. Use the “max hold” to keep the sweep signals on the screen
and the peak table function to list the peak signals across the bandwidth. These are typical
operations to cache transient signals. This demonstration shows how you can easily
configure the N9310A to generate a pulse modulation signal and set the pulse period from 200 microseconds
to 2 seconds for use – for example, an EMC test or component test. To generate the pulse
modulation signal set the center frequency and amplitude of the signal generator. Then
enter the pulse modulation mode and set the pulse period and pulse width. When you activate
the “pulse on” and “RF on”, the pulse modulation signal is generated. Set the center
frequency, span, and RBW of the N9320B to see the pulse signal on the screen. Switching the N9320B to zero-span may help
you understand the signal from the viewpoint of time domain. You can use the delta marker
to measure the pulse width of the pulse signal. The Agilent N9310A provides 4 types of analog
modulation: amplitude, frequency, phase, and pulse. This demonstration focuses on frequency
modulation, which is widely used in broadcasting, wireless, electronic device, toy manufacturing
and EMC testing. First, select the carrier frequency and amplitude.
Next, select the FM modulation parameters, which include the FM deviation and FM rate.
Finally, activate the mode and RF output. Now the FM signal is being generated. You
can use the marker table to list the frequency points of interest. If you want to better understand your analog
signal, the N9320B option AMA provides the AM and FM demodulation metrics, including
carrier power, modulation rate, AM depth, FM deviation, SINAD and carrier frequency
offset. The Agilent N9310A signal generator has an
optional broadband IQ modulator, and is able to generate digital signals in conjunction
with an external IQ source. The output signal can be measured with the N9320B spectrum analyzer. In this demonstration, two 33250A arbitrary
waveform generators are used to generate digital-based band IQ signals, and these IQ signals are
input into the N9310A to produce RF signals. At first we generate a GMSK signal, which
is widely used in GSM communication systems. We measure the channel power or occupied band
power with the N9320B built in one-button PowerSuite, which helps you finish the test
setup simply by pressing one button. The PowerSuite not only shortens the learning curve, but
also helps ensure the accuracy of the test setup. Now we change the configuration to produce
FSK signal. The N9320B option DMA supports the demodulation of ASK and FSK signals, and
also provides readouts for the base band symbols, RF waveforms, ASK/FSK errors, and I-diagrams.
The digital signal generation and demodulation can be widely used for manufacturing a variety
of wireless products, such as cordless phones, two-way radios, RFIDs and wireless mice. The optional tracking generator adds a new
dimension of power to the N9320B spectrum analyzer. This demonstration shows how the
tracking generator lets you measure the insertion loss of a filter. Turn on the tracking generator
mode and set the start and stop frequencies. Set the output power to -10 dBm. Reduce the
resolution bandwidth to increase measurement sensitivity and smooth the noise. Activate
the tracking Peak to correct the frequency offset between the output frequency of the
tracking generator and the input frequency of the analyzer. Connect the cable from the
tracking generator output to the analyzer input. Next, store the frequency response in trace
four and normalize to eliminate the effect of the test environment. Reconnect the filter
to the analyzer and change the normalized reference position. The marker readout displays
the insertion loss of the filter at specific frequencies. The N9320B also provides a straightforward
way to measure the 3 dB bandwidth of your DUT with just one button press. To learn more about RF circuit design, circuit
characterization and communication systems, Agilent offers the N9320B-TR1 RF Training
Kit option, which can be used with the N9310A and N9320B. This out-of-box training tool
includes 2 boards – one acts as a transmitter circuit and the other one serves as a receiver
circuit. The major RF components on each board can be used as separate standalone components. Using Agilent’s flexible RF education solution
is convenient, time saving and cost effective. This solution uses the N9310A RF signal generator,
N9320B RF spectrum analyzer, a transmitter and receiver unit and the RF training software.
The RF signal generator generates an input signal to the transmitter unit, and the spectrum
analyzer measures the output signal of receiver units. Using just the transmitter unit, we
input a 50 MHz signal. We have an onboard 818 MHz frequency synthesizer, and the board’s
output connection is to a spectrum analyzer where we see an 818 MHz signal. Now let’s take this step by step down the
transmitter board. First, we look at the output of the mixer. We can see on the spectrum analyzer
that there is an 868 MHz signal at the output of the mixer. However, there are many byproduct
signals. Consequently, we have to filter out the unwanted signals. The next step is to move the analyzer to the
output of the band-pass filter, and we can see it blocks many of the unwanted signals.
However, the power of the 868 MHz signal is -28 dBm. Since this power level is too low
to transmit over the air, we need to amplify it. We move the spectrum analyzer to the power
amplifier section, and can then see the 868 MHz signal at -19 dBm level, but there are
other signals present and we are not allowed to transmit the signal over the air. At this stage we need to do a final filtering
to remove the unwanted signals. At last, we connect the antenna to the output of the transmit
unit and measure the output of the receiver unit. This successfully recovers the transmitted
50 MHz signal and completes our basic demonstration of one of the system’s capabilities. Agilent’s low-cost compact N9310A signal
generators and N9320B spectrum analyzers deliver all the capability and reliability of spectrum
Agilent instruments at a price too good to pass up. Visit our website for a closer look
at how valuable the N9310A signal generator and N9320B spectrum analyzer can be in meeting
your measurement requirements.
