itrans

Configures and launches current transients consisting of
2 sequential steps of load current with specified
durations. Optionally produces trigger out. There is no
memory of trigger mode – must be specified on each
instance of usage.
i1
,
i2
: specify current entry for step 1 and 2 respectively.
t1
,
t2
: specify duration entry for step 1 and 2 respectively.
current1
is first current value in units of mA (0 to 512
mA).
duration1
is first duration value (range 1m to 1000m or
200u to 1000u where “m” is mSec and “u” is
μ
Sec.)
current2
is second current value in units of mA (0 to 512
mA).
duration2
is second duration value (range 1m to 1000m
or 200u to 1000u where “m” is mSec and “u” is
μ
Sec.)
duration2
may also take the value “hold” causing the
current load to sustain indefinitely at the
current2
value instead of returning to original static load.
go
= launch current transient
trig1
= start current transient on next trig1 event
ext
= start current transient on next ext trigger event
trigout
= generate event trigger on command execution

trig1
<
port

Configures and/or arms the edge trigger for operation.
Default configuration is Rising, 15 VDC, Not Armed.
Trig1 is also used as start to time interval measurements.
r ising
sets trigger to respond to rising edge on PoE bus.
falling sets trigger to fire on falling edge on PoE bus.
l evel
specifies trigger level setting to follow
trigLevel
trigger level in voltage with range of 0 to 64
VDC in with resolution of 0.25 V.
a rm
enables start trigger to trigger once when input
conditions are satisfied. Trigger will then reset.
c lear
disables start trigger until arm re-enables it.
nor mal
(
future setting PSA-3000
) configures edge trigger
for 0.125V noise immunity. Ignored by PSA-1200.
noi sy
(
Future setting PSA-3000
) configures edge trigger
for 0.5V noise immunity. Ignored by PSA-1200.

Trigger 2 is
only used
as end criteria to all time interval
measurements. Trigger is armed when Trig1 is armed.
r ising
sets trigger to respond to rising edge on PoE bus.
f alling
sets trigger to respond to falling edge on PoE bus.
l evel
specifies trigger level setting to follow
trigLevel
trigger level in voltage with range of 0 to 64
VDC in with resolution of 0.25 V.

trigout
<
port
>
Generate immediate external trigger out from the port.
With PSA-1200 controller firmware
version 1.63 or later, port may be “0,0” meaning event triggers will be sourced from PSA
controller and arrive exactly in tandem to all available test ports.
pstatus
<
port
>
Returns LED status of the selected port. Values are
ON
or
OFF
for DET, PWR, ARM, and AUX LED’s. The DET
LED indicates if port switch is closed and valid detection
resistance and capacitance are present. PWR indicates
that the PSE port is powered up. ARM indicates that the
triggering is an ARMed state. AUX is command activity.
stat
LED Status of
selected port.
