Performance Verification Tests
41. Tracking Generator Absolute Amplitude and Vernier Accuracy: Agilent E4401B and
E4411B (Option 1DN or 1DQ)
41. Tracking Generator Absolute Amplitude
and Vernier Accuracy: Agilent E4401B and
E4411B (Option 1DN or 1DQ)
A calibrated power sensor is connected to the tracking generator output
to measure the power level at 50 MHz.
The power meter is set to relative mode so that future power level
readings are in dB relative to the reference power level setting. The
output power level setting is decreased in 1 dB steps and the
power level is measured at each step. The difference between the ideal
and actual power levels is calculated at each step.
Since a power sweep is accomplished by stepping through the vernier
settings, the peak-to-peak variation of the vernier accuracy is equal to
the power sweep accuracy.
The related adjustments for this performance test are “Tracking
Generator ALC Calibration” and “Tracking Generator Frequency
Slope.”
Equipment Required
Power meter, compatible with power sensor
RF power sensor, 50 Ω
Additional Equipment for Option 1DQ
Power sensor, 75 Ω
Adapter, Type-N (f) to BNC (m), 75 Ω
Adapter, Type-N (f), 75 Ω to Type-N (m), 50 Ω
Procedure
CAUTION Use only 75 Ω cables, connectors, or adapters on instruments with 75 Ω
connectors, or damage to the connectors will occur.
For Agilent E4411B analyzers, this test must be performed at 20 to
30° C.
1. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Set the analyzer by pressing the following keys:
FREQUENCY, Center Freq, 50 MHz
