Memory recall
There are three types of recall: carrier, full and RAM. Both carrier and full stores are non-volatile.
The contents of the RAM store are lost when the instrument is switched off.
Carrier recall
The non-volatile carrier frequency store has 100 locations numbered 0 to 99 for carrier frequency
only. These can be recalled and used in conjunction with full recall to apply a set of test
conditions to a range of frequencies.
Full recall
The non-volatile full store has 100 locations numbered 100 to 199 for the storage of instrument
settings. These stores may be recalled and used to reset the instrument’s parameters to those
which affect the RF output: carrier frequency, RF level, modulations in use, on/off and source
information and the two modulation oscillator frequencies in use.
RAM recall
The volatile RAM store has locations numbered 200 onwards for the full storage of instrument
settings. The parameters that are recalled are the same as those for full recall.
Recalling data
To recall data, press the [RCL] key and enter the location number on the key pad, then press
[ENTER]. Depending on which location range the number falls in, the display shows FREQ (for
carrier store), FULL or RAM. The [×÷10] and [Ø×10] keys as well as the control knob can be
used to recall the next and previous locations.
Recalling default settings
To recall the factory default settings, press the [RCL] key and enter 999 on the keypad, then press
[ENTER]. The RESET annunciator is shown and the instrument is reset to the settings shown in
Table 4-1.
