Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'A1'
Create channel 4 and a trace named Ch4Tr1 to measure the
wave quantity a1.
CALC4:PAR:SEL 'Ch4Tr1'
Select Ch4Tr1 as the active trace
.
OUTP4:DPOR PORT2
Select drive port 2 for the active trace.
OUTPut<Ch>:UPORt[:VALue] <numeric_value>
Sets or queries a channel-dependent four-bit binary value to control four independent output signals at
the USER CONTROL connector (lines 8, 9, 10, 11). The output signals are 3.3 V TTL signals which can
be used to differentiate between up to 16 independent analyzer states.
OUTPut<Ch>:UPORt[:VALue]
itself does not change the analyzer state.
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.
•
The value defined with
OUTPut<Ch>:UPORt[:VALue]
is assigned to channel no. <Ch>.
•
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
channel bits is started. They are changed whenever a channel with different channel bits
becomes the measuring channel.
•
The signals at the USER CONTROL connector are maintained after the analyzer enters the
hold state. This happens if all channels use single sweep mode and if all sweep sequences
have been terminated.
You can use the active channel number as a parameter for
OUTPut<Ch>:UPORt[:VALue]
and
monitor the activity of up to 16 different channels at the USER CONTROL connector; see example
below. You can also use the USER CONTROL output signals as channel-dependent trigger signals for
external devices. Use
CONTrol:AUXiliary:C[:DATA]
to transfer the four bit value in decimal
representation.
<Ch> Channel number.
<numeric_value>
Binary value.
