47. Fast Time Domain Sweeps, HP 8591EM Option 101 and Option 301

Procedure

Fast Sweep Time Amplitude A ccuracy

1.Connect the equipment as shown in Figure 2-69.

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

4FREQUENCY5 300 4MHz5

4SPAN5 0 4Hz5

4SWEEP/TRIG5 20 4ms5

4AMPLITUDE5 SCALE LOG/LIN (LIN) REF LVL 25 4mV5

4MKR5 More 1 of 3 More 2 of 3 MK NOISE ON OFF (ON)

4SGL SWP5

4MKR5 MARKER 1

3.Set the sweep time to 18 ms. Press 4SGL SWP5 and read the MKR 1 amplitude. Record the marker-1 reading as TR Entry 1 of the performance veri￿cation test record. The amplitude should be within 1.007X and 0.993X.

Fast Sweep Time Accuracy

4. Connect the equipment as shown in Figure 2-70.

5.Set the signal generator to output a 300 MHz, 04 dBm, CW signal. Set the AM and FM controls to OFF.

6.Set the synthesizer/level generator to output a 556 Hz, +5 dBm, signal.
