6. Noise Sidebands, HP 8590 EM-Series

4MKR5 MARKER NORMAL

Record the MKR amplitude reading in the Noise Sideband Worksheet as the Noise Sideband Level at 020 kHz.

3.Record the more positive value, either Noise Sideband Level at +20 kHz or Noise Sideband Level at 020 kHz from the Noise Sideband Worksheet as the Maximum Noise Sideband Level at 620 kHz.

4.Calculate the Noise Sideband Suppression at 20 kHz by subtracting the Carrier Amplitude from the Maximum Noise Sideband Level at 620 kHz. Use the equation below.

Noise Sideband Suppression = Maximum Noise Sideband Level 0 Carrier Amplitude

5.Record the Noise Sideband Suppression at 20 kHz in the performance

veri￿cation test record as TR Entry 2. The suppression should be ￿070 dBc.

Part 3: Noise Sideband Suppression at 30 kHz

1.Press the following EMC analyzer keys to measure the noise sideband level at

+30 kHz:
