Selecting the Output Voltage Programming Source and Output Mode
Select the Output Voltage Programming Source
The EXT-AC and EXT-DC modes require the optional analog interface board (option
AC68BALGU). You cannot use the analog output interface board with the GPIB interface
because both boards use the same slot.
Without the analog interface board, only the Internal option is available. This controls the output
voltage by the instrument. The Internal option is also selected by
.
EXT_AC configures the instrument to behave as a variable gain amplifier controlled by an external DC
level. The internal frequency control remains in effect.
EXT_DC mode configures the instrument to behave as a fixed gain power amplifier. Internal controls
for voltage and frequency are disabled.
You cannot set the voltage limit when the instrument is being controlled by external
analog signals. An excessive external voltage may damage the load.
