Low Noise Amplifiers for
Power Level Accuracy Adjustment and Performance Test
The power level accuracy adjustment and performance test both use low noise amplifiers.
They are required to maintain separation between a low-level signal and the signal
analyzer noise floor. The following amplifiers meet the requirements of making this
measurement.
A +15 Vdc external supply is required for each of the amplifiers. An HP/Agilent E3615A,
0 to 20 V power supply can power all recommended amplifiers simultaneously.

2Operation Verification
This chapter provides procedures that will either ensure that the signal generator is
operating correctly or will help to point to problem areas if it is not. Operation verification
does not ensure performance to specifications, but should provide a level of confidence that
the signal generator is operating correctly within a minimum amount of time. Operation
verification is appropriate for incoming inspection, after repair when a full calibrated
performance is not required, or whenever the integrity of the signal generator is in
question.

Equipment Required
• HP/Agilent 5350A Frequency Counter
• HP/Agilent 438A Power Meter
• HP/Agilent 8482A Power Sensor
• HP/Agilent 8563E Spectrum Analyzer
• HP/Agilent 8491A/B Option 006 Attenuator (6 dB)

1. Power On the Signal Generator
This procedure verifies that the signal generator powers up and that the internal
instrument check identifies no errors. The internal check evaluates the correctness of
operation and returns an error message if a problem is detected.
1. Turn power on to the signal generator by pressing the power switch. The green LED
will light. Let the signal generator warm up for one hour.
NOTE For ESG-AP or ESG-DP signal generators, or those with Option 1E5, ERROR
514, Reference Oven Cold occurs whenever the signal generator is first
connected to AC line power. The
annunciator both turn on. The OVEN COLD annunciator automatically clears
after approximately 5 minutes. The error queue cannot be cleared, however,
until the OVEN COLD annunciator has turned off.

2. Cycle the power to the signal generator. The green LED should again be lit and the
signal generator will perform a check.

2. Check for Error Messages
1. When the display is lit, check to see if the ERR annunciator is turned on.
2. If the

ERR annunciator is turned on, review the error messages in the queue by pressing
shown in the text area of the display. Refer to the error messages guide for information
about the error message.
If there is more than one error message (each message will be designated as 1 of n),
continue pressing the
View Next Error Message softkey until you have seen all of the
messages.
3. When you have resolved all of the error messages, press Clear Error Queue(s) to delete the
messages. Cycle the power on the signal generator and then restart this procedure
(Check for Error Messages) at step 1.
3. Frequency Range and Accuracy Check
Frequency range is tested by determining the frequency accuracy relative to the timebase
at the frequency limits.

50Ω.
NOTE Set the gate time of > 5 seconds for maximum counter accuracy. Verify that
the counter is phase-locked to the 10 MHz external reference.
Measure the Frequency Accuracy
1. Set the signal generator to the frequencies shown in Table 2-1, “Frequency Accuracy,”
on page 2-10 (to the maximum frequency of your signal generator).
2. Record the measured frequency in Table 2-1 and compare it to the corresponding limits.
4. Power Level Accuracy Check
Performing this check will provide a high level of confidence that the signal generator’s
power level circuitry is functioning correctly. This check does not test the signal generator
to warranted specifications. Test points have been reduced and the limits are degraded in
order to minimize measurement time and take into account a broad range of measurement
uncertainties. To have the signal generator tested to warranted specifications, a complete
power level accuracy performance test is required. If the complete performance test is
needed and you are unable to perform it, contact your nearest Agilent Technologies service
center for information concerning calibration.

Configure the Power Meter
1. Zero and calibrate the power meter to the sensor’s reference calibration factor.
2. Set the power meter to measure absolute log power (dBm).
Measure the Power Level Accuracy
1. Set the power levels and frequencies for the signal generator (to the maximum
frequency of your signal generator). Refer to the appropriate table in the following list:
• Table 2-2, “Power Level Accuracy Setup 1 (Signal Generators without Option 1E6),”
on page 2-11
• Table 2-3, “Power Level Accuracy Setup 1 (Signal Generators with Option 1E6),” on
page 2-13.
2. Set the power sensor’s calibration factor for each frequency.
3. Record the measured power level in the appropriate table (Table 2-2 or Table 2-3) and
compare it to the corresponding limits.

Operation Verification ESG Family Signal Generators
Verification Procedures
Configure the Signal Generator
1. Press Frequency. Enter 277 using the numeric keypad and press the kHz terminator
softkey.
2. Press Amplitude. Enter −15 using the numeric keypad and press the dBm terminator
softkey.
Configure the Spectrum Analyzer
1. Preset the spectrum analyzer.
2. Set the analyzer to external 10 MHz reference.
3. Set the center frequency to 277 kHz.
4. Set the frequency span to 100 Hz. (This will result ina1Hzresolution bandwidth with
a digital filter.)
Measure the Power Level Accuracy
1. Connect the signal generator’s RF OUTPUT through the 6 dB attenuator to the
spectrum analyzer’s RF input.
2. Transfer the power level results for each frequency at −15 dBm from the Measured
Power column in Table 2-2 or Table 2-3 as appropriate, to the Power Meter Reading for
−15 dBm column in Table 2-4, “Power Level Accuracy Setup 2 (All Signal Generators),”
on page 2-15.
3. On the spectrum analyzer, select
Marker Normal Mode and then select the Peak Search
function. This activates the marker and sets it to the signal peak.
4. On the spectrum analyzer, ensure that the marker is at the signal peak and use the
MKR-> menu to set the marker to the reference level. If necessary, select Peak Search to
ensure that the marker is at the signal peak.
5. With the marker at signal peak, select the Marker Delta function. This will set the marker
to measure relative amplitude from a reference of 0 dB. If the marker does not read
0 dB, press
Marker Normal > Peak Search > Marker Delta until the marker reads 0 dB.
6. Decrease the signal generator amplitude in 10 dB steps as shown in Table 2-4. At each
10 dB step, select Peak Search to ensure that the marker is at the signal peak.
7. Measure the power levels shown in the Power Level Setting (dBm) column of Table 2-4
for the current frequency, and record the values in the Spectrum Analyzer Marker (dB)
column.
8. Return the spectrum analyzer reference level and the signal generator amplitude to
−15 dBm. Set the signal generator frequency and the spectrum analyzer’s center
frequency to the next frequency listed in Table 2-4 and repeat the process from step 3.
Continue until all of the frequencies have been measured and recorded (to the
maximum frequency of your signal generator).

ESG Family Signal Generators Operation Verification

Calculate the Actual Power Level
1. Calculate and record the Actual Power Level, in Table 2-4, as the sum of the Power
Meter Reading for −15 dBm and the Spectrum Analyzer Marker (dB) value.
For example:
• Power Meter Reading for −15 dBm at 2.516 MHz = −14.95 dBm
• Spectrum Analyzer Marker (dB) at 2.516 MHz and Power Level Setting at
−85 dBm = −70.17 dB
• Actual Power Level at 2.516 MHz and −85 dBm: (−14.95) + (−70.17) = −85.12 dBm
2. Compare the calculated Actual Power Level value to the corresponding limits.
