External Triggering (Model 2306-VS Only) 6-9
TRIGger[1]:EXTernal:STEP <NRf1,NRf2,NRf3> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP <NRf1,NRf2,NRf3> Applies to charger channel (#2)
These commands set the voltage and delay values for a given step.
<NRf1> is the step number being configured. This parameter has
a minimum setting of 1 and
a maximum setting of 20.
<NRf2> is the voltage value for the step specif
ied with <NRf1>.This parameter has a mini-
mum setting of 0 and a maximum setting of 15 volts with a default value of 0 for each step.
<NRf3> is the delay setting for the step specif
ied with <NRf1>. This parameter has a mini-
mum setting of 0 and a maximum setting of 5 seconds with a default setting of 0 for each step,
and may be set in 10μs
step increments.
The NRf parameters must be comma separated with
no spaces after the comma and start of
the next parameter. An error will occur if spaces are placed after the commas. For example,
TRIG:EXT:STEP 1,1.2,.1 will configure step 1 on channel 1 for 1.2 volts with a delay of
100 ms. However, TRIG:EXT:STEP 1, 1.2,.1 will generate an error
message because of the
spaces between parameters
An error message is generated if all three
parameters are not sent. If less than three parameters
are sent, the unit will generate a parameter missing error message. If more than three parameters
are sent, the unit will generate a too much data error message. If NRf1 and NRf2 are valid
parameter values, the voltage value for specified step NRf1 is updated regardless of the validity
if NRf3. If NRf1 is invalid, voltage or delay settings are not changed. However, if NRf1 is valid
and NRf2 is invalid, the voltage and delay setting for the NRf1 step are not changed.
The trigger delay for each step must elapse completely before any other functionality is pro-
cessed. If waiting for a delay on a channel to elapse,
the other channel will not be serviced.
TRIGger[1]:EXTernal:STEP? <NRf> Applies to battery channel (#1)
TRIGger2:EXTernal:STEP? <NRf> Applies to charger channel (#2)
These commands query the voltage and delay setting for a given step, or query the MINimum,
MA
Ximum, and DEFault settings. For example, TRIG:EXT:STEP? 1 will return the following
(using the above set example), “1,1.200000E+00,1.00000E-01”. Another example is
TRIG:EXT:STEP? MAX, which returns “20,1.500000E+01,5.00000E+00”.
TRIGger[1]:EXTernal:STEP? Applies to battery channel (#1)
TRIGger2:EXTernal:STEP? Applies to charger channel (#2)
These commands query for the next step number to be completed upon detection of the trig-
ger in pulse with external trigger enabled. The power
-up value is 1, and the value is set to 1 each
time trigger external is enabled after being disabled. The query value will also be 1 while waiting
for the INIT command when taking measurements.
