ANALOG MODULATION MODE
3-88
Full store
Selecting
[Full Store]
enables the storage of a complete instrument setting, i.e. carrier frequency,
RF level, modulations and their increments, ON/OFF and source information. Also stored are all
6 modulation oscillator frequencies, plus one increment, and the LF Generator Monitor setting.
There are 50 locations (numbered 0 to 49) for full storage. A further location (50) holds the
factory default settings. This memory cannot be written to by the user. The factory default
settings are listed in Table 4-1.
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
All six internal oscillator frequency settings
The modulation frequency step size
LF generator frequency setting
LF generator frequency step size
LF generator level setting
LF generator level step size
LF monitor settings
Display blanking settings
In digital and vector modes the parameters are stored in place of the analog modulation
parameters.
Partial store
This is a less comprehensive store 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. There are 50 locations
(numbered 0 to 49) for partial storage.
A Partial Store contains the following information:
Carrier frequency setting
RF level setting
The active modulation settings
Modulation mode and status
The frequency of the active modulation frequencies
Either the LF generator frequency and level setting or the LF monitor setting (depending
on which mode is selected)
In digital and vector modes the parameters are stored in place of the analog modulation
parameters.
Carrier store
The carrier frequency store has 100 locations (numbered 0 to 99) for the storage of carrier
frequency only. This store can be used in conjunction with the full and partial stores to apply a set
of test conditions to a range of frequencies.
Sweep store
The sweep store has 20 locations (numbered 0 to 19) for the storage of complete sets of sweep
parameters.
