Description
12 /PORT A7 I or O Port A, bit no. 7
13 /PORT B0 I or O Port B, bit no. 0 (8-bit parallel input or output port)
14 /PORT B1 I or O Port B, bit no. 1
15 /PORT B2 I or O Port B, bit no. 2
16 /PORT B3 I or O Port B, bit no. 3
17 /PORT B4 I or O Port B, bit no. 4
18 /EXTERNAL
TRIGGER
I External trigger signal
19 /PORT B5 I or O Port B, bit no. 5
20 /PORT B6 or
/INDEX
I or O
O
Port B, bit no. 6
The /INDEX signal changes to "Low" when a measurement is complete (all sweeps in
all channels have been performed; the DUT can be removed, but the measurement
results may not be valid yet).
21 /PORT B7 or
/READY FOR
TRIGGER
I or O
O
Port B, bit no. 7
The /READY FOR TRIGGER signal changes to "Low" when the analyzer is ready to
receive a trigger for a new measurement.
22 /PORT C0 I or O Port C, bit no. 0 (4-bit parallel input or output port)
23 /PORT C1 I or O Port C, bit no. 1
24 /PORT C2 I or O Port C, bit no. 2
25 /PORT C3 I or O Port C, bit no. 3
26 /PORT D0 I or O Port D, bit no. 0 (4-bit parallel input or output port)
27 /PORT D1 I or O Port D, bit no. 1
28 /PORT D2 I or O Port D, bit no. 2
29 /PORT D3 I or O Port D, bit no. 3
30 /PORT C STA-
TUS
O
Indicates the status of port C:
●
Low: port C is an input port
●
High: port C is an output port
31 /PORT D STA-
TUS
O
Indicates the status of port D:
●
Low: port D is an input port
●
High: port D is an output port
32 /WRITE
STROBE
O Changes to "Low" when valid data is present at any of the output ports (i.e. when the
output level at any port changes).
33 /PASS FAIL O
Indicates the status of the global limit check for the last measurement:
●
Low: global limit check failed
●
High: global limit check passed
Other configurations are possible; see CONTrol:HANDler:PASSfail... commands.
34 /SWEEP END O Indicates the end of the measurement. Changes to "Low" after all sweeps in all chan-
nels have been completed and the measurement data has been processed. Alternative
configurations: see CONTrol:HANDler:SWEepend.
