Amplitude Accuracy At 50 Mhz - Keysight N9000A Service Manual

Functional Tests

Amplitude Accuracy at 50 MHz

Amplitude Accuracy at 50 MHz
Test Limits
Amplitude Accuracy should remain within 1.13 dB of the measured source value
across the range of source levels and changes in resolution bandwidth. The Preamp
(option P03, P07) should remain within ±1.3 dB of measured values.
A synthesized sweeper is used as the signal source for the test. The source
amplitude is varied using the signal source amplitude control. The attenuation and
resolution bandwidth are varied on the signal analyzer. The source amplitude is
measured by the power meter and signal analyzer at each setting, and the values
compared. The difference between each pair of measurements indicates the
amplitude accuracy.
