OD Output the display
Syntax:
OD
Remarks:
Outputs a formatted display channel reading in either dBs or Watts. Will
also output the cal factor tables, as described below.
The only way to read out the cal factor table data from the HP 437 is to
send the commands to display each entry on the screen, and then ask for
a text display output using the 'OD' command.
The ML2430A Series supports the 'OD' command to the extent that it will
output a formatted display channel reading in either dBs or Watts, and will
also output the cal factor tables. After sending the 'ETn' command (n = the
cal factor table number) if an 'OD' is sent, the first frequency/cal factor
entry of the cal factor table is output in the HP format. If this is then
followed by an 'EN' the next cal factor entry pair is available for output, and
can be read using the 'OD' command. When all the pairs are output, all
further 'ENOD' combinations output a frequency of '00.00 MHz 100.0%'.
The EX command terminates this action so that further 'OD' commands
now output the display reading in a formatted mode.
If RFnOD (n = cal factor table number) is sent, the 50 MHz cal factor table
entry is output.
OF Offset state
