Procedure - Keysight 537A Operating Note

Overall Accuracy

Procedure

1 Connect the equipment as shown in
2 Set oscilloscope for a vertical sensitivity of about 02 V/cm (ac) and horizontal sensitivity of
about 1 V/cm.
3 Set sweep oscillator for ^F automatic sweep of about 3.8 GHz + 12 MHz for 537A.
4 Set the 537A to 3.8 GHz.
5 Locate the frequency meter notch and center it on the display by adjusting the sweep limits on
the sweep oscillator.
6 Set the sweep oscillator to CW and adjust the frequency to the center of the notch (lowest
indication on the oscilloscope).
7 Read the frequency on the counter. Frequency should be within the specifications given in
Table
8 Repeat above procedure every 200 MHz across the band.
9 Set sweep oscillator to automatic sweep and tune the 537A across frequency range of sweep
oscillator. The notch travel across the frequency range should cause at least the notch depth
given in
20
