b. Measure residual response:
H
Press the LINES key.
H
Press the Show Line side key to select Vertical .
H
Press the Number Of Line key to select 1 .
H
Press the
Line1
side key and set the value to 100 MHz.
H
Press the Show Line side key to select Horizontal .
H
Press the
Number Of Line
key to select
1
.
H
Press the Line1 side key and set the value to --90 dBm using the
numeric keypad.
c.
Check against limits: Confirm that the residual signal level is --90 dBm
or less at 100 MHz or more.
4. Check residual response in the RF1 band for RSA3308A only:
a. Modify the analyzer controls:
H
Press the
SPAN
key on the front panel.
H
With the
Stop Freq
side key, set the frequency to 3.5 GHz using the
numeric keypad.
b. Measure residual response: Press the PEAK key to place the marker at
the peak on the noise floor.
c. Check against limits: Read the marker readout. Confirm that the residual
signal level is --90 dBm or less within the whole bandwidth.
5.

a.
Modify the analyzer controls:
H
Press the FREQUENCY/CHANNEL key on the front panel.
H
With the Center Freq side key, set the frequency to 5 GHz using the
numeric keypad.
b.
Measure residual response: Press the
PEAK
key to place the marker at
the peak on the noise floor.
c.
