POWER MEASUREMENT
Option 02 measures the power of signals applied to Band
3.
The power
is
displayed (to 0.1 dB resolution)
simultaneously with frequency (to 100 kHz max. resolution). For A.M. and F.M. averaging purposes,
gate time is controllable in the power meter mode, through the resolution function. Power gate time
mirrors frequency gate time. For example, in resolution
0 the frequency gate time
is
1 second, and the
power gate time
is
1
second. In resolution 1 the frequency gate time
is
100 msec., and the power gate
time
is
100 msec. Option 02 allows power offsets from
-99.9
dB to
99.9
dB, with
a
0.1 dB resolution
and will not degrade the basic performance of the counter.

If the counter
is
displaying only frequency
it
will begin displaying frequency and power. If the counter
is
displaying frequency and power it will begin displaying frequency only.
Turn the power meter on. Observe the display. Frequency
is
displayed on the left, and power is displayed
on the right. The POWER
dBm annunciator lights to indicate power meter operation. If the signal
is
too small to measure the power, the display will show EE.E in the power meter digits. (Since 0 dBm is
a
valid power, 00.0 can not be used as a no power indicator.)
Power meter offsets are entered and displayed in the same manner as other data. Refer to the Display
and Data Entry Sequence in Section
3.
