Press the Shift key followed by pressing the Measure (4) key on the numeric keypad to
open the Measure menu.
2.
Press the More submenu key to open the Measure 2/2 menu.
3.
Press the Tracking Generator submenu key to open the Tracking Generator menu.
Selecting Vector Signal Generator Mode
1.
Press the Shift key followed by pressing the Mode (9) key on the numeric keypad to
open the Mode Selector list box.
2.
Use the directional arrow keys or the rotary knob to highlight the Vector Signal
Generator mode, then press the Enter key to select.
Caution

Chapter 2 — Tracking Generator
(Option 20)
2-1
Introduction
The Tracking Generator operates over a frequency range of 100 kHz to 7.l GHz, and provides
a signal with an output frequency that is the same as the tuning frequency of the MS2721B
spectrum analyzer. The output power and level accuracy are specified from 450 kHz to
7.1 GHz. When the spectrum analyzer is set to zero span, the output is a CW signal. The
output power is leveled and can be adjusted from 0 dBm to –40 dBm in 0.1 dB steps.
2-2
Tracking Generator Operation
1.
Press the Track Gen Off/On submenu key to turn On and Off the output of the tracking
generator. The output power turns on at the level that has been set previously with the
Output Power submenu key.
2.
Press the Output Power submenu key and set the output power (at the output
connector) from 0 dBm to –40 dBm, in 0.1 dB steps. The output is leveled and flat over
the specified frequency range of the tracking generator.
3.
If you change a setting and want to restart the sweep, press the Reset Sweep submenu
key. The sweep restarts at the lowest frequency that is selected and also restarts
Averaging.
2-3
Measurement Example
This example demonstrates how to calibrate the instrument and make a measurement.
1.
Set the frequency range to cover the range of the DUT being tested. In this example,
the center frequency is set to 1.96 GHz with a 500 MHz span.
2.
The Tracking Generator can become slow if sweep detection is set to any method other
than Sample. To set the detection method to Sample, press the Shift key, then the
Sweep (3) key. Then press the Detection submenu key and press Sample for the fastest
sweeps.
3.
Press the Shift key, then the Measure (4) key.
4.
Press the More submenu key to open the Measure 2/2 menu.
5.
Press the Tracking Generator submenu key.
6.
Press the Track Gen Off/On submenu key to turn on the output of the tracking
generator (the current state, On or Off, is underlined on the submenu key display).
7.
Press the Output Power submenu key and set the output power for the device that is
being measured, from 0 dBm to –40 dBm, in 0.1 dB steps. In this example, which is
measuring a band pass filter, the power level is set to 0 dBm in order to get the
maximum signal through the filter. (The band pass filter that was used in this example
Signal Generators MG

Measurement Example
Tracking Generator (Option 20)
is similar to the 1850 MHz to 1910 MHz, 50 ohm band pass filter, Anritsu part number
1030-111-R).
8.
Connect the DUT between the RF Out and RF In connectors on the instrument. Use
good quality cables and adapters to make the connections.
9.
Observe the measurement to confirm that the frequency range covers the frequency
range that was intended.
Figure 2-1.
Measurement Before Normalization
10. If the spectrum analyzer noise floor is too high for the necessary measurements, then
reduce the input attenuation and RBW to maximize the dynamic range. Probably, the
scale will need to be changed from 10 dB/division to a higher value to see the stop band
of a good filter. In this example, the scale is changed to 15 dB/division in Step 17 (as
shown in Figure 2-5 on page 2-5).
11. When measuring a filter with a very high insertion loss in the stop band, press the Shift
key, then the Trace (5) key. Press the Trace A Operations submenu key, then the
Average → A submenu key to turn on averaging and clean up the stop band area. An
averaging value of 10 will probably be adequate for most filters.

Measurement Example
Instrument Set for Good Measurement Before Normalization
12. After the frequency range and other settings are satisfactory, disconnect the DUT and
make a THROUGH connection between the RF Out and RF In connectors. For the most
accurate results, use the same cables and adapters for this connection as were used to
connect the DUT.
13. Confirm that the display shows a nearly flat signal when the THROUGH is connected.
If the signal is not reasonably flat, then verify that the cables and connections are in
good condition and that the connectors are properly tightened.
14. Press the S21 Insertion Loss submenu key.
15. Press the Normalize submenu key to set Normalization On (the current state, On or Off,
is underlined on the submenu key display).

Flat Sweep After Normalization (Relative Scale at 10 dB/division)
16. Figure 2-3 shows the THROUGH measurement after normalization. Note the relative
scale numbers on the graticule lines (in increments of 10 dB) on the right side of the
sweep window now that Normalization is ON. If desired, the resolution bandwidth and
video bandwidth can be changed after normalization without needing to renormalize. If
the input attenuation is changed, then a new normalization sweep is required. After
the normalization sweep is finished, reconnect the DUT between the RF Out and RF In
connectors. Figure 2-4 shows the filter measurement after normalization.

Chapter 3 — Vector Signal Generator
(Option 23)
3-1
Introduction
The BTS Master with Option 23 offers a Vector Signal Generator (VSG) with the capability of
generating a single waveform or two different waveforms within a 10 MHz bandwidth. Each
waveform can be a CW signal, or can have analog, digital, and custom modulation.
3-2
Signal Generator Features
• 400 MHz to 6 GHz
• –124 dBm to 0 dBm, CW Single Channel
• –124 dBm to –8 dBm, modulated, noise, or multicarrier (multichannel)
• One signal to 10 MHz bandwidth, or two signals to 5 MHz bandwidth each, plus
Additive White Gaussian Noise (AWGN)
• Wideband AWGN Noise Source (approximately 15 MHz bandwidth)
The level control range for any active channel is –124 dBm to 0 dBm, within the limitations
of the total power specification. The VSG produces a minimum power level of
–124 dBm per channel, where each signal is considered to be a channel (for example, signal 1,
signal 2, and noise). The maximum power specification is 0 dBm for a single CW signal,
–8 dBm for a single modulated signal, and –8 dBm total for multi-channel operation. Note
that noise channel power is included when considering the total power.

Modulation patterns are available for both the signal patterns and the interferer patterns.
These patterns are presented in a dialog box, which is shown in Figure 3-5, “Custom
Modulation Configuration” on page 3-11.
To open the “Custom Modulation Configuration” dialog box. press the Modulation main menu
key, then press either the Signal Pattern submenu key or the Interferer Pattern submenu key,
then press the Custom submenu key. Refer to Figure 3-14 on page 3-18, Figure 3-15, and

Signal Pattern and Interferer Pattern
Set up the signal and interferer patterns to one of three types of modulation: analog, digital,
or custom.
In the following 3 procedures, the signal pattern or interferer pattern is chosen.
Analog Modulation Pattern Setup
In the following procedure, you are directed to choose a Modulation Type, a Rate, and a
Deviation for a signal pattern, or you are directed to choose a Modulation Type, a Frequency,
and a Depth for an interferer pattern. When selected, these parameters are displayed in the
lower section of the sweep window. Refer to “Signal Data” and “Interferer Data” in Figure 3-1
on page 3-5.
1.
From the Modulation menu, and after pressing either the Signal Pattern or the
Interferer Pattern submenu key, press the Analog submenu key. The Analog Modulation
Configuration dialog box opens with the Modulation Type list box highlighted in red. The
following figure is an example only. Your instrument may show a different list.
