16.Absolute Amplitude Calibration and Resolution (IF) Bandwidth Switching Uncertainties,HP 8590 EM-Series

Absolute Amplitude Uncertainty

1.Connect the CAL OUT to the EMC analyzer input using the BNC cable and adapter, as shown in Figure 2-19.

2.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Set the EMC analyzer controls by pressing the following keys:

4SPAN5 10 4MHz5

4MKR !5 MARKER ! HIGH

4MKR5 More 1 of 3 MK TRACK ON OFF (ON)

4FREQUENCY5 300 4MHz5

4SPAN5 50 4kHz5

4BW5 3 4kHz5

AVG BW AUTO MAN (MAN) 300 4Hz5

4AMPLITUDE5 87 4+dB￿V5

SCALE LOG LIN (LIN)

(For HP 8594EM, HP 8595EM, and HP 8596EM only)

More 1 of 3 More 2 of 3 COUPLE AC DC (DC)

3.Press 4MKR !5, MARKER ! HIGH , then record the marker reading in TR Entry 1 of the performance veri￿cation test record.

The marker reading should be within 86.85 and 87.15 dB￿V.
