NOTE
There is a residual response at 1 MHz. Tuning to 1.02 MHz to
avoid displaying the response will yield a displayed average
noise indication worse than the actual noise at 1 MHz.
(15) Add -2.27 dB to TI MKR amplitude indication. Calculated displayed average
noise level will be <-140 dBm.
(16) Press TI keys and enter values using DATA keys as listed in (a) through (g) below:
(a)
FREQUENCY and then [START FREQ] to 10 MHz.
(b)
[STOP FREQ] to 2.9 GHz.
(c)
MARKER MKR [MARKERS OFF].
(d)
CONTROL BW then [RES BW] to 1 MHz.
(e)
[VIDEO BW] to 10 kHz.
(f)
[VID AVG ON OFF] to select OFF.
(g)
INSTRUMENT STATE SGL SWP and wait for completion of new sweep.
(17) Press TI keys and enter values using DATA keys as listed in (a) through (j) below:
(a) MARKER MKR then [MKRNOISE ON OFF] to select ON.
(b) MARKER PEAK SEARCH.
(c) [MARKER → CF].
(d) SPAN then [SPAN] to 375 Hz.
(e) CONTROL BW then [RES BW] to 1 Hz.
(f) [VIDEO BW] to 1 Hz.
(g) [VID AVG ON OFF] to select ON.
(h) CONTROL TRIG then [SWEEP CONT SGL] to select CONT.
(i) CONTROL TRACE then [CLEAR WRITE A] and wait until VAVG 5 is
displayed above the gradicule.
(j) INSTRUMENT STATE SGL SWP and wait for completion of new sweep.
(18) Add -2.27 dB to TI MKR amplitude indication. Calculated displayed average
noise level will be <-151 dBm.
(19) Press TI keys and enter values using DATA keys as listed in (a) through (f) below:
(a) FREQUENCY then [START FREQ] to 2.9 GHz.
(b) [STOP FREQ] to 6.46 GHz.
(c)
MARKER MKR then [MARKERS OFF].
(d)
CONTROL BW then [RES BW] to 1 MHz.
(e)
[VIDEO BW] to 10 kHz.
(f)
[VID AVG ON OFF] to select OFF.
(20) Repeat (17) above.
