WJ-P718-19/FE HF RECEIVER
INSTALLATION AND OPERATION
2.4.9.3
Count Pulses;
Slew Up and Count Pulses:
Slew Down
The COUNT PULSES: SLEW UP or COUNT PULSES: SLEW DOWN operation
causes the receiver's tuned frequency to step up or down in frequency steps equal to
the current IF bandwidth at a rate equal to the COUNT PULSES rate.
The operation
is subject to the limitation that the COUNT PULSES can not change at a rate faster
than once every 100 msec.
If COUNT PULSES are bursted the receiver cannot change
at a rate faster than once every 100 msec.
The state of the SQUELCH OUT line during the COUNT PULSES: SLEW UP
or COUNT PULSES: SLEW DOWN operation will be the same as previously described
in Paragraph 2.4.9.2, as are the frequency end point limitations.
Figure 2-10 shows
the timing relationship for the remote COUNT PULSES: SLEW DOWN operation.
