4. Press the UTIL key, and press HELP again. Since entering the
utility menu does not affect the measurement display, the first
part of the help screen will be the same as in step 2. The last part
of the help screen, however, will now describe the utility menu
function keys rather than presets as in 1 channel mode.
5. Exit help by pressing ESC.
E. Measurements Overview
Steps F–J guide a new user through some basic measurements. Refer
also to an explanation of readouts, on pages 2–8 and 2–8. Here is a
list of the measurements that can be made:
1 CHAN provides the visual and aural carrier levels for one channel
you select.
PILOTS mode provides graphic and numeric readouts of the visual
levels at two frequencies you define as low and high pilots.
5 CHAN displays the visual levels of the five preset frequencies you
define.
ALL CHAN provides an overview of all the channels in the active
channel table (selected through the UTIL menu). All channel mode
measurement results are used as sweep references.
METER is a simulated analog display which also allows monitoring
of the FM audio signal.
C/N simultaneously displays the carrier level and carrier-to-noise
ratio for the tuned channel.
HUM displays the visual carrier level and percent of peak-to-peak
hum for the tuned channel.
FM DEV measures the peak deviation of the aural carrier.
SPECT has a tunable marker and readout of the marker fre-
quency and signal amplitude.
SWEEP provides system-referenced sweep measurements, with a
peak-to-valley readout between two tunable marker frequencies.
SEQ allows execution of automated test sequences.
