CONTrol:AUXiliary:C[:DATA]). Up to 2 x 8 = 16 additional channel bits are available.
0 to 255 [–]
The transferred values correspond to the following states of the Universal
Interface connector:
0 – no channel-dependent (dynamic) signal at any of the pins A7 ... A0 or B7
... B0; the static configuration of the output ports A and B is unchanged
1 – additional dynamic output signal at pin A0 or B0
2 – additional dynamic output signal at pin A1 or B1
3 – additional dynamic output signal at pin A0 and A1 or B0 and B1
...
255 – additional dynamic output signal at pins A7 ... A0 or B7 ... B0
Device-specific, command or query
CONTrol:HANDler:A:DATA 192
Write a static bit pattern 1100 0000 to port A.
INSTrument:NSELect 1; :CONTrol:AUXiliaty:A:DATA 1
INSTrument:NSELect 2; :CONTrol:AUXiliaty:A:DATA 2
INSTrument:NSELect 3; :CONTrol:AUXiliaty:A:DATA 3
Select channel no. 1, define a bit pattern 1 for channel 1. Repeat this for
channels no. 2 and 3, using the bit patterns 10 and 11, respectively.
While channel 1 is measured, the output port A is configured according to the
bit pattern 1100 0001. While channels no. 2 and 3 are measured, the bit
patterns are 1100 0010 and 1100 0011, respectively.
CONTrol:AUXiliary:C[:DATA] <numeric_value>
Sets or queries a channel-dependent eight-bit decimal value (channel bits) to control up to eight
independent output signals at the USER CONTROL connector (pins 8 to 11 and 16 to 19). The output
signals are 3.3 V TTL signals which can be used to differentiate between up to 256 independent states.
By default pins 16 to 19 are not used as channel bits (OUTPut<Ch>:UPORt:ECBits OFF), which leaves
16 possible states.
Channel bit definition and activation
The channel bits have the following properties:
After a *RST of the analyzer all channel bits (including the value for the active, sweeping channel
no. 1) are set to zero; no signal is applied to pins 8 to 11 of the USER CONTROL connector and
pins 16 to 19 are not used as extra channel bits.
The value defined with CONTrol:AUXiliary:C[:DATA] is assigned to the active channel
(INSTrument:NSELect <Ch>). Setting the value does not change the analyzer state.
The signals at the USER CONTROL connector reflect the channel bits of the measuring channel,
i.e. the channel for which the analyzer performs a sweep. This channel is not necessarily identical
with the active channel.
The signals are switched on as soon as a measurement (sweep) in a channel with non-zero
