Example:
*RST; :SEGM:INS 1MHZ, 1.5MHZ, 111, -21DBM,
0.5S, 0, 10KHZ
Create a sweep segment no. 1 with a sweep range between 1.0
MHz and 1.5 MHz.
SWE:TYPE SEGM
Set the segmented frequency sweep active.
OUTP:UPOR:SEGM:STAT ON
Enable segment bits.
OUTP:UPOR:SEGM1 #B0001
Assign the segment bit value #B0001 to segment no. 1. The out-
put signal at pin 16 is switched on while the first segment is
measured.
SEGM2:ADD
Create a second sweep segment. The frequency range of the
second segment will be between 1.5 MHz and the maximum fre-
quency of the analyzer.
OUTP:UPOR:SEGM2 #B0010
Assign the segment bit value #B0010 to segment no. 2. While
the analyzer measures the second segment, the output signal
changes from pin 16 to pin 17.
Manual operation:
See
OUTPut<Ch>:UPORt[:VALue]
<BinValue>
Sets or queries a channel-dependent eight-bit binary value to control eight independent
output signals at the USER PORT connector (lines 8, 9, 10, 11 and lines 16, 17, 18,
19). The output signals are 3.3 V TTL signals which can be used to differentiate
between up to 255 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 and 16
to 19 of the USER PORT connector.
●
The value defined with
OUTPut<Ch>:UPORt[:VALue]
is assigned to channel no.
<Ch>
.
●
The signals at the USER PORT connector reflect the channel bits of the
measur-
ing
channel, i.e. the channel for which the analyzer performs a sweep. This chan-
nel 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 differ-
ent channel bits becomes the measuring channel.
●
The signals at the USER PORT 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.
