Model 2308 Portable Device Battery/Charger Simulator User’s Manual Section 3: Pulse Current Measurements
:DELay <NRf> Specify trigger delay in seconds:
0.0–0.1 (pulse current measurements) or
0.0–5.0 (pulse current digitization).
0.0
:STEP <b> Performs a series of measurements

Pulse current
step method )
OFF
:UP <NRf>
<0-20> (max is for both up and down combined) 1
:DOWN <NRf> <0-20> (max is for both up and down combined) 1
:TIME <NRf> 33.3

:TimeOUT <NRf>
TimeOUT (other than the first): 2msec–200msec 2 ms
:INITial <NRf>
First TimeOUT step: 10msec–60secs 2 sec
:DELay <NRf> 0msec–100msec (in 10msec steps) 0
:SEQuence
<NRf, NRf> Define up to 19 delay sequence values using the
index and the time value (e.g. "1,1e-3" sets the first delay to
1ms). Ranges: 1-19 (parameter 1) and 0 to 100e-3
(parameter 2).
0
:LENgth <NRf>
Define the delay sequence length (0 to 19). Specify
zero to always use the
PCUR:STEP:DELay
value.
0
:SKIP <b> Specify whether (1) or not (0) to skip sequential
triggers.
1=Only requires 1 trigger
0 = Requires multiple triggers
0
:TLEVx <NRf>
Set trigger level for each TLEV step where x equals
1–20 (the maximum settings are based on the selected
current range. Therefore, the current range must be
selected before setting the step trigger level values)
0.0
:FAST Enable or disable pulse current fast readings. OFF
:SEARch
Enable or disable pulse current search. ON
:DETect
Enable or disable pulse current detection mode. OFF
:TimeOUT Specify length of timeout: 5ms - 32s incrementing in
1ms.

SENSe2
SENSe subsystem for charger channel (#2):
:FUNCtion “PCURrent”
Select pulse current measurement function. VOLT
:PCURrent Pulse current configuration:
:AVERage <NRf> Specify average count:
1 to 100 (pulse current measurements), or
1 to 5000 (pulse current digitization). 1
:MODE <name> Select measurement mode; HIGH, LOW or AVERage. HIGH
:TIME
Set integration times:
:AUTO
Integration times set automatically.
:HIGH <NRf> Specify integration time (in sec) for high pulse
measurements; 33.33e-6 to 0.8333.
