Section 9: Measurement Commands and Optimizing Measurement Speed
Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Overview
The signal-oriented measurement commands are used to acquire readings. You can use these
high-level instructions to control the measurement process. These commands are summarized in
Table 9-1
.
Table 9-1
Signal-oriented measurement command summary
Command
Description
:FETCh[1]?
Returns the last reading from battery channel (#1). Triggered before
reading(s).
:FETCh[1]:ARRay?
Returns the last array of readings from battery channel (#1). Triggered
before reading(s).
:FETCh2?
Returns the last reading from charger channel (#2). Triggered before
reading(s).
:FETCh2:ARRay?
Returns the last array of readings from charger channel (#2). Triggered
before reading(s).
:READ[1]?
Triggers and returns a new battery channel (#1) reading.
:READ[1]:ARRay?
Triggers and returns a new array of battery channel (#1) readings.
:READ[1]:AMP?
Switch to 5A range then take a measurement on battery channel (#1).
:READ[1]:HUNDred?
Switch to 500mA range then take a measurement on battery channel
(#1).
:READ[1]:FIFTy?
Switch to 50mA range then take a measurement on battery channel
(#1).
:READ[1]:FIVE?
Switch to 5mA range then take a measurement on battery channel (#1).
:READ2?
Triggers and returns a new charger channel (#2) reading.
:READ2:ARRay?
Triggers and returns a new array of charger channel (#2) readings.
:MEASure[1][:<function>]?
Performs a
READ?
on the specified battery channel (#1) function.
:MEASure[1]:ARRay[:<function>]?
Performs a
READ:ARRay?
on the specified battery channel (#1)
function.
:MEASure2[:<function>]?
Performs a
READ2?
on the specified charger channel (#2) function.
:MEASure2:ARRay[:<function>]?
Performs a
READ2:ARRay?
on the specified charger channel (#2)
function.
BOTHTRG
Triggers a reading on channel 1 and then channel 2. After this
command completes, the display is set for Channel #2.
BOTHFUNC <name>
Sets the battery channel (#1), then the charger channel (#2), to the
function specified by <name>. Valid strings for name are “VOLTage”,
“CURRent”, “PCURrent”, or “LINTegration”. Since "DVMeter" is a
charger-only function, sending this command with a name such as
"DVMeter" will generate a string data error (-150) message.
BOTHFETCH?
Responds with channel 1 and channel 2 readings in a single message.
The message contains a value for channel 1, a comma, and then a
value for channel 2. After this command completes, the display is set
for Channel #1.
BOTHREAD?
Triggers reading on channel 1 and then channel 2, then responds with
channel 1 and channel 2 readings in a single message. The message
contains a value for channel 1, a comma, and then a value for Channel
#2. After this command completes, the display is set for Channel #2.
