(10) Press TI keys and enter values using DATA keys as listed in (a) through (h) below:
(a) FREQUENCY then [CENTER FREQ] to 10 kHz.
(b) AMPLITUDE then [REF LVL] to -70 dBm.
(c) MARKER MKR [MARKERS OFF].
(d) CONTROL TRIG then [SWEEP CONT SGL] to select CONT.
(e) CONTROL TRACE then [CLEAR WRITE A] and wait until VAVG 5 is
displayed above the graticule.
(f) INSTRUMENT STATE SGL SWP and wait for completion of new sweep.
(g) MARKER MKR to 10 kHz.
(h) [MKRNOISE ON OFF] to select ON.
(11) Add -2.27 dB to TI MKR amplitude indication. Calculated displayed average
noise level will be ≤-120 dBm.
(12) Press TI keys and enter values using DATA keys as listed in (a) through (g) below:
(a) FREQUENCY then [CENTER FREQ] to 99 kHz.
(b) MARKER MKR [MARKERS OFF].
(c) CONTROL TRIG then [SWEEP CONT SGL] to select CONT.
(d) CONTROL TRACE then [CLEAR WRITE A] and wait until VAVG 5 is
displayed above the graticule.
(e) INSTRUMENT STATE SGL SWP and wait for completion of new sweep.
(f) MARKER MKR to 99 kHz.
(g) [MKRNOISE ON OFF] to select ON.
NOTE
There is a residual response at 100 kHz. Tuning to 99 kHz to
avoid displaying the response will yield a displayed average
noise indication worse than the actual noise at 100 kHz.
(13) Add -2.27 dB to TI MKR amplitude indication. Calculated displayed average
noise level will be <-120 dBm.
(14) Press TI keys and enter values using DATA keys as listed in (a) through
(g) below:
(a) FREQUENCY then [CENTER FREQ] to 1.02 MHz.
(b) MARKER MKR [MARKERS OFF].
(c) CONTROL TRIG then [SWEEP CONT SGL] to select CONT.
(d) CONTROL TRACE then [CLEAR WRITE A] and wait until VAVG 5 is
displayed above the graticule.
(e) INSTRUMENT STATE SGL SWP and wait for completion of new sweep.
(f) MARKER MKR to 1.02 MHz.
(g) [MKRNOISE ON].
