Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Section 2: Basic Power Supply Operation
[SOURce1]:CURRent <n>
Applies to battery channel (#1)
SOURce2:CURRent <n>
Applies to charger channel (#2)
With a milliamp measurement range selected, the maximum current limit is 1A. For the battery
channel, these ranges are 5 mA, 50 mA, or 500 mA. The charger channel range is 5 mA.
[SOURce[1]]:CURRent:STATe?
Applies to battery channel (#1)
SOURce2:CURRent:STATe?
Applies to charger channel (#2)
1. With the LIMit type selected, this command returns a “1” if the power supply is operating as
a constant-current source (current limit reached). With the TRIP type selected, a “1” is
returned if the output has turned off (tripped) due to current limit being reached. It will clear
to “0” when the output is turned back on.
2. The operation event register can be read to determine if the power supply is in current limit
and if the output has tripped (turned off) as a result of the current limit condition. See
Section 7
for details.
OUTput[1]:IMPedance <NRf>
Applies to battery channel (#1)
This battery channel only command may be set from 0–1
Ω
in 0.01
Ω
steps. The command can be
used with the output ON or OFF.
OUTput[1]:BANDwidth <name>
Applies to battery channel (#1)
OUTput2:BANDwidth <name>
Applies to charger channel (#2)
This command specifies HIGH or LOW bandwidth. You can program the bandwidth at any time.
BOTHOUTON
Turns both channels ON
BOTHOUTOFF
Turns both channels OFF
When sending either command, make note that the command is applied to battery channel (#1)
first and then to charger channel (#2). This allows both channels’ output state to be controlled with
a single bus command while preventing the outputs from being turned ON or OFF simultaneously.
No short form exists for this command.
NOTE
Sending a value that exceeds 1 A will generate a parameter out of range error
message (-222).
NOTE
The bandwidth query will return user-specified settings, not necessarily the
present instrument value. Refer to
Table 2-2
for how output state settings affect
the actual bandwidth configuration.
