F1: GPIB
- (optional) Selects the GPIB remote mode of operation. After selection the GPIB address can be
set to any value from 1 to 31 using the rotary knob. The value is kept in a nonvolatile memory and
used at power-on. The factory default address is 9. Setting the address to 31 puts the device in the
off-bus state (it will not respond to messages on the GPIB bus).
F1:RS232 - Selects the RS232 remote control mode. After selection, the baud rate can be selected as
2400, 9600, and 19200. The RS-232 uses 8 bit data, 1 stop bit and no parity.
F2: RECALL - Recalls a previously stored front-panel setup from the selected buffer. Change the buffer
number by using the rotary input knob. Valid storage buffer numbers are from 0 to 49.
Buffer 0 is the factory default setup.
F2: STORE - Stores the current front-panel setup to the specified storage buffer. Change the buffer
number by using the numeric keypad or the rotary input knob. Valid storage buffer
numbers range from 1 to 49. Below is a list of parameters that can be stored in each
buffer.
Note: Location 50 is for last working setup before power down.

*For power-on setting, channel output status is not saved and cannot be recalled. For example, if
channel output is ON when storing into memory, it cannot be recalled when that memory is set for
power-on setting. In which case, at power on status of the channel output will always be disabled.
This is for safety reasons because in some cases, if device connected to the generator is sensitive
to signal level, accidentally powering the instrument ON with the output on may damage the
device right away.
**The RECALL and STORE function can be used as a tool to store and locate many arbitrary
waveforms. Because the 4075 and 4078 are designed with one large memory bank (up to 400,000
