Memory stores
Carrier store
The non-volatile carrier frequency store has 100 locations numbered 0 to 99 for the storage of carrier frequency only. This store can be used to apply a set of test conditions to a range of frequencies. For example, if you wish to use the same modulation at a variety of frequencies you can use the carrier store to set the instrument to each of the frequencies in turn. When a carrier store is recalled it will only replace the current carrier frequency - all the other settings will remain unchanged.
Full store
The non-volatile full store has 100 locations numbered 100 to 199 for the storage of instrument settings. This store is used to store those parameters which currently affect the RF output; carrier frequency, RF level, modulations in use, on/off and source information and the two modulation oscillator frequencies in use.
A full store contains the following information: Carrier frequency setting Carrier frequency step size RF level setting
RF level step size
All modulation settings All modulation step sizes Modulation mode and status
The active modulation frequencies The modulation frequency step size All sweep settings
RAM store
The volatile RAM store has 100 locations numbered from 200 to 299 for the full storage of instrument settings. The parameters stored are the same as those for the full store. However, the RAM store has no long term wear-out mechanism and is therefore recommended for use in ATE programs where all the settings to be used in a test sequence are initially declared and then recalled. This results in a reduction of the 488.2 message overhead.
