THReshold
THReshold command/query
The THReshold command allows you to set the voltage threshold for a
given pod to ECL, TTL or a specific voltage from -9.9V to + 9.9V in 0.1
volt increments.
p’ On the HP 1650B, the pod thresholds of pods 1,2, and 3 can be set
Note ti * d
m ependently. The pod thresholds of pods 4 and 5 are slaved together;
therefore, when you set the threshold on pod 4 or 5, both thresholds will
be changed to the specified value. On the HP 1651B, both pods 1 and 2
can be set independently.
The THReshold query returns the current threshold for a given pod.
Command Syntax: :MACHine{ 112):TFORmat:THReshold c N z {TTLI ECLl <value z-1
where:
<N> ::= pod number (112131415)
<value> :: = voltage (real number) -9.9 to +9.9
TTL :: = default value of + 1.6V
ECL :: = default value of -1.3V
Example: OUTPUT XXX;“:MACHlNEl:TFORMAT:THRESHOLD14.o”
Query Syntax: :MACHine{ lI2):TFORmat:THReshold < N z-?
Returned Format: [:MACHine{l~2}:TFORmat:THReshold<N>] <value> <NLs
Example: 10 DIM Value$ [loo]
20 OUTPUT XXX;":MACHINEl:TFORMAT:THRESHOLDE?"
30 ENTER XXX;Value$
40 PRINT Value$
