2-14 Basic Power Supply Operation
[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 operat-
ing as a constant-current source (current limit reached). W
ith 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 0–1Ω in 0.01Ω steps. The com-
mand 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
an
y time. However, when the output is OFF or the current range is 5mA for the
Model 2306 and 2306-VS (or 500mA for the battery channel on 2306-PJ), the band-
width is set to LOW. (See Table 2-2.)
NOTE The bandwidth query will return user-specified settings, not necessarily the present
instrume
nt value.
BOTHOUTON Turns both channels ON
BOTHOUTOFF Turns both channels OFF
NOTE These commands are available starting in
firmware release version B02. Use the
Model 2306 REVISION NUMBER menu item (located on the main menu) to display
the firmware revision for the microcontroller and the display.
When sending either command, make note that the command is applied to channel 1
(battery
channel) first and then to channel 2 (charger channel). 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.
