This subsystem provides device-specific commands to control the "Universal Interface", option R&S ZVAB-B14. The pin assignment of the Centronics 36 rear-panel connector of this option is shown below. For a detailed description refer to section Universal Interface.

The setting commands write data to ports A, B, C, D. To write data to a port, the port must be configured as an output port (see example). The port lines have negative logic: A "0" at a pin corresponds to a high signal, a "1" to a low signal.
The queries read data from ports A, B, C, D. If the port is an output port, the queries return the last value that was written to the port.
<decimal>
Decimal representation of an n-bit binary value.
Range
Port A: 0 to 255 (pins A7 ... A0)
Port B: 0 to 255 (pins B7 ... B0)
Port C: 0 to 15 (pins C3 ... C0)
Port D: 0 to 15 (pins D3 ... D0)
The parameters MIN, MAX, DEF are not supported.
*RST value
0 (port A and B) Ports C and D are configured as input ports
Note: *RST or Preset do not change the configuration of the Universal Interface. Use CONTrol:HANDler:RESet to restore default values.
SCPI, Command Types
Device-specific, command or query
Example 1:
CONT:HAND:A:MODE OUTP
Configure port A as an output port.
CONT:HAND:A 192
Write data to port A.
CONT:HAND:B:MODE INP
Configure port B as an input port.
CONT:HAND:B?
Read data from port B.
Example 2:
Use the output ports A or B for channel monitoring; see CONTrol:AUXiliary:A[:DATA]?
Controls the direction of the data flow at ports A, B, C, D.
Parameters
INPut – Input of data at the port OUTPut – Output of data at the port
Port A and B: OUTPut Port C and D: INPut
Example:
See CONTrol:HANDler:A[:DATA]
Selects the digital signal that is routed to pin 20 of the Universal Interface connector.
<Boolean>
ON – /INDEX signal at pin 20 OFF – /PORT_B6 signal at pin 20
OFF
CONT:HAND:EXT:IND:STAT ON
Route the /INDEX signal to pin 20.
CONT:HAND:EXT:RTR:STAT ON
Route the /READY_FOR_TRIGGER signal to pin 21.
CONT:HAND:RES
Restore the default state: Pins no. 20 and 21 are available for port B input/output signals.
Selects the digital signal that is routed to pin 21 of the Universal Interface connector.
ON – /READY_FOR_TRIGGER OFF – /PORT_B7 signal at pin 21
See CONTrol:HANDler[:EXTension]:INDex:STATe
Writes a 0 or 1 to the output ports (pin 3 or 4) of the Universal Interface connector. The port lines have negative logic: A "0" corresponds to a high signal, a "1" to a low signal.
The query reads the last value that has been written to the output port.
<port>
Output port number:
1 – /OUTPUT1 (pin 3) 2 – /OUTPUT2 (pin 4)
<binary>
0 – high 1 – low
0
CONT:HAND:OUTP2:DATA 0
Set the /OUTPUT2 line (pin 4) to 0 (current state of /OUTPUT2).
CONT:HAND:OUTP2:USER 1
Define the next state of the /OUTPUT2 line as 1 (low). /OUTPUT2 will go from 0 to 1 when the analyzer receives a negative pulse on the /INPUT1 line (pin 2).
Defines the state of the output ports (pin 3 or 4) of the Universal Interface connector after the next negative pulse on the /INPUT1 line (pin 2).
See CONTrol:HANDler:OUTPut<port>[:DATA]
Restores the default states of the CONTrol:HANDler... commands including the data port values.
