31. Spurious Responses: Agilent E4402B and E4403B
AMPLITUDE, Ref Level, –20 dBm
BW/Avg, Video BW, 30 Hz
(Man)
9. On the analyzer, press
BW/Avg, Average, 10 Hz. Wait until “VAvg 10”
is displayed along the left side of the display.
10.On the analyzer, press
Peak Search (or Search). The marker delta (∆
Mkr1) amplitude reading is the second harmonic suppression.
11.Calculate the 900 MHz Second Harmonic Intercept (SHI) using the
second harmonic suppression value read in step 10 and the 300 MHz
Frequency Response Error (FRE) from Table 2-73 as follows:
For example, if the second harmonic suppression is –73 dB, and the
900 MHz FRE is 0.70 dB, the SHI would be 52.3 dBm:
12.Record the 900 MHz SHI as Entry 4 in the performance verification
test record.
900 MHz SHI 20 dBm– Second Harmonic Suppression 900 GHz FRE+–=
