OUTPut:UPORt[:VALue] #B00000000 to #B11111111
This command sets the control lines of the user ports. In manual operation, the control lines are
represented by softkeys PORT 0 to 7.
The user port is written to with the given binary pattern. If the user port is programmed to INPut instead
of OUTPut, the output value is temporarily stored.
Example:
"OUTP:UPOR #B10100101"
Characteristics: *RST value: -
SCPI: device-specific
Mode: R, A

Operating Manual 1302.6163.12 - 03
With the tracking generator switched on, the maximum stop frequency is limited
to 3 GHz. This upper limit is automatically modified by the set frequency offset
of the generator.
If measurements in compliance with specs are to be performed with the tracking
generator, the start frequency has to be ≥3 x resolution bandwidth.
The minimum sweep time for measurements in compliance with the data sheet
is 100 ms in the frequency domain (span >0). If a shorter sweep time is
selected, the sweep time indicator SWT on the screen is marked with a red
asterisk and the message UNCAL is also displayed.
