Memory recall
Pressing the [MEM] hard key after switch on, causes the
Memory Recall Menu
, Fig. 3-82, to be
displayed. There are four types of recall, full, partial, carrier frequency and sweep. Provision is
made for an option not to recall the carrier frequency for full and partial stores. This allows one
carrier frequency to be used with a series of stored settings. Pressing
[Inhibit ON/OFF]
turns the
option ON and OFF. The state of the option is indicated on the display.

Full recall
Selecting
[Full Recall]
enables the recall of a complete instrument setting, i.e. carrier frequency,
RF level, modulations and their increments, ON/OFF and source information. Also recalled are all
6 modulation oscillator frequencies, plus one increment, and the LF Generator/Monitor setting.
[Inhibit ON/OFF]
provides the option not to recall the carrier frequency setting. The state of the
option is indicated on the display. There are 50 locations (numbered 0 to 49) for full recall. A
further location (50) allows the factory default settings to be recalled. The factory default settings
are listed in Table 4-1.
Partial recall
This is a less comprehensive recall of only those parameters which currently affect the RF output;
carrier frequency, RF level, modulations in use (without increments), ON/OFF and source
information and the two modulation oscillator frequencies in use. As with full store, the option
not to recall the carrier frequency is provided. There are 50 locations (numbered 0 to 49) for
partial storage.
Carrier recall
The carrier frequency store has 100 locations (numbered 0 to 99) which may be recalled when
required.
Sweep recall
The sweep store has 20 locations (numbered 0 to 19) containing complete sets of sweep
parameters which may be recalled when required.
Sweep parameters can be recalled whether the instrument is in sweep mode or not. They
are only used when sweep is selected.
