Figure 10-8: Timing of measurement control signals
The figure above corresponds to the default configuration of the /PASS FAIL signal.
For alternative configurations refer to the documentation of the
CONTrol:HANDler:PASSfail...
commands in
on page 851. The figure contains the following pulse durations and response
times.
Time
Description
Value
T1
Pulse duration of /EXTERNAL TRIGGER
Minimum value: 1 μs
T2
Response time of /PASS FAIL STROBE
1 μs
T3
Pulse duration of /PASS FAIL STROBE
1 μs
T4
Pulse duration of /SWEEP END
12 μs
The timing of the data port signals and the input/output signals is as follows:
●
The low pulse of the /WRITE STROBE signal occurs approx. 0.1 μs after a value is
written to the output ports A to D. The pulse duration of the /WRITE STROBE sig-
nal is 1 μs.
●
The low pulse of the /OUTPUT 1 or /OUTPUT 2 signals (if enabled) occur approx.
0.6 μs after the falling edge of the /INPUT 1 signal.
10.2.5 RFFE - GPIO Interface
For the R&S
ZNB an optional RFFE - GPIO interface board is available (R&S
ZN-B15/
Z15).
