Description
Description
The E4402/7B HSB provides an LO OUT between 2.1 GHz to 3.1 GHz
at a power level of ≥ 5 dBm.
Verifying the Shipment
After the instrument has been unpacked, it is recommended that the
original packaging materials are kept so they may be used if the
instrument should need to be transported.
Inspect the instrument for any signs of damage that may have occurred
during shipment. If your instrument appears to be damaged, see
“Contacting Agilent”on page 26 for the nearest office.

Operation
Operation
The E4402/7B Option HSB Spectrum Analyzer and the Tektronics (Tek)
1405 TV Sideband Adapter are fully compatible. The operational range
of the spectrum analyzer falls within the operating parameters of the
Tek 1405 TV Sideband Adapter. Refer to the Tek 1405 instrument
manual for specifications and operating parameters.
Before You Begin
Press the following keys on the spectrum analyzer:
[SYSTEM] > More > Show System
NOTE The following typeface conventions are used throughout this document.
Hardkeys are shown with brackets as follows:
•[HARDKEY] are labeled front panel keys
•SOFTKEYS are unlabeled keys whose function is indicated on the
instrument display.
Connecting to the Spectrum Analyzer
The following set-up is one example of how a typical measurement may
be performed using the E4402/7B Spectrum Analyzer with the Option
HSB. Refer to Table 1-1, “Material and Equipment Required,”for a list
of equipment needed.

Operation
1. Connect one end of the SMA cable (5062-6674) to the Tek 1405 TV
Sideband Adapter LO IN to the SMA connector labeled “2.1–3.1 GHz
LO Out”on the rear panel of the E4402/7B Spectrum Analyzer. Refer
to Figure 1-1.
2. Attach the BNC cable (8120-2582) from the Video Out on the rear of
the Tek 1405 Sideband Adapter to the Video In on the transmitter or
modulator under test.
3. Secure the appropriate adapters to the ends of the BNC cable
(8120-2582) and attach to the 50 ΩRF Input of the E4402/7B
Spectrum Analyzer and the other end to the output of the modulator.
CAUTION A directional coupler or high power attenuator may be needed to keep
the DUT output power from exceeding +30 dBm or 1 W max safe input.

Making Measurements
The instructions describe the setup for a simple measurement that may
be made using the equipment listed in Table 1-1 and the configuration
in Figure 1-1, “E4402/7B Option HSB Test Hardware Setup”.
1. Turn On all of the equipment. Allow the equipment to warm up for
the required specified time as indicated in each of the instrument
operating manuals.
2. Turn Off the Auto Align routine before making your measurements.
Perform the following keystrokes:
[System] > Alignments > Auto Align > Off
3. Select the desired channel on the modulator, or use the assigned
transmitter frequency. Channel two ( ≈ 55.25 MHz) has been selected
for this example.
4. Perform the following keystrokes:
[Frequency] > Start Freq > [52 MHz] > [Frequency]
Stop Freq > [63 MHz].
After you have completed the setup, refer to Figure 1-2 for an
example of the waveform on the screen of the E4402/7B.

Operation
5. Slowly adjust the Tek 1405 course “Transmitter Frequency”knob to
the desired frequency. Use the “Fine”adjust knob if more accuracy is
desired. The waveform displayed on the E4402/7B Spectrum
Analyzer will display the bandwidth of the transmitter or modulator
under test, see Figure 1-3. Refer to the Tek 1405 documentation for
more information on making measurements.

Performance Verification
Performance Verification
The purpose of the electrical test is to verify the response of the HSB
option card in the ESA. The HSB option card provides an output
frequency range from 2.1 GHz to 3.1 GHz with a power level ≥ 5 dBm.
Equipment Required
•Spectrum Analyzer. Use a spectrum analyzer with a frequency
range of > 4 GHz.
•ESA Spectrum Analyzer containing Option HSB (DUT).
•RF Cable (3.5 mm).
1. Turn on both spectrum analyzers and press [Preset].
2. Turn off the Auto Align function of the DUT and the test spectrum
analyzer, if so equipped.
3. Connect the HSB Output, on the rear of the ESA DUT, to the RF
Input, on the spectrum analyzer using an RF cable and adapter, if
required.
4. Press [Frequency] on the ESA DUT and set the start frequency to
0 Hz and the stop frequency to 1.1 GHz.
5. Press [Frequency] on the test spectrum analyzer and set the start
frequency to 1.7 GHz and the stop frequency to 3.3 GHz.
6. Set the RF level on the test spectrum analyzer to 30 dBm.
7. Increase the test spectrum analyzer sweep time to approximately
20 seconds for improved display clarity.
8. Leave all other ESA DUT and test spectrum analyzer settings
autocoupled.
9. Set the test spectrum analyzer markers 1 and 2 to frequencies of
2.1 GHz to 3.1 GHz, respectively.
10. Press [View Trace] > Max Hold on the test spectrum analyzer.

16 User’s and Service Guide Supplement
Performance Verification
11. Verify that the test spectrum analyzer signal trace is ≥5 dBm
between 2.1 GHz and 3.1 GHz. Refer to Figure 1.
Figure 1-4 Option HSB Trace Characteristics
12. Press [Span] > Zero Span on the ESA DUT.
13. Press [Center Frequency] [0 MHz] on the ESA DUT.
14. Press [View/Trace] > Clear Write on the test spectrum analyzer.
15. Set the [Marter] on the test spectrum analyzer to 1.8214 GHz.
16. Verify that the test spectrum analyzer signal trace is < –15 dBm at
1.8214 GHz. The HSB board LO signal must be attenuated
sufficiently for proper sideband adapter operation.

Repair Information
Repair Information
The HSB can occupy Slot 5 or 6 and will appear to be empty. Note that
Slot 6 actually contains the Option HSB. Verify that Option HSB has
been installed by checking the serial tag on the rear panel of the
instrument.
