BOP-1K 111315 B-27B.95 [SOURce:]VOLTage:MODE COMMAND VOLT:MODESyntax: Short Form: [SOUR:]VOLT:MODE (FIX | LIST | TRAN | EXT | GAIN | PROT | HALT)Long Form: [SOURce:]VOLTage:MODE (FIXed | LIST | TRANsient | EXTernal | GAIN | PROTect |HALT)nn = = time in Seconds for transient (from 0.0005 to 2)Description: Allows the user to execute or stop a list, to execute a transient, or to use an external referencein voltage or current mode of operation. The default mode is FIXed: the power supply executes com-mands normally, and LIST commands can be issued to establish the parameters and sequence of a list.This command affects the main channel, whether voltage or current.When VOLT:MODE LIST is issued, a list is executed (See LIST commands and Figure B-5). Whilethe list is being executed, LIST commands are not accepted and will produce a command error.Issuing VOLT:MODE FIX while the list is running will stop the execution of the list and return powersupply to settings in effect prior to running the list. If the list runs to completion, the settings of the laststep of the list will be in effect.Issuing VOLT:MODE HALT while the list is running will stop the execution of the list at the end of thecurrent cycle.VOLT:MODE TRAN nn causes the next VOLT: or CURR: command to produce a transient pulse ofnn Seconds duration, after which the voltage returns to original value. E.g., VOLT:25 sets the output to25 volts, and VOLT:MODE TRAN 0.1 primes the unit for a transient of 0.1 Seconds. When VOLT:10 isissued, the power supply output goes to 10V for 0.1 Seconds. Similarly, sending VOLT:TRIG 14,VOLT:MODE TRAN .05 and *TRG causes the output to go to 14V for 0.05 Seconds. If the time nnexceeds 2 Seconds, error message -222 “dwell or frequency out range” is posted to the error queue.VOLT:MODE EXT Configures the unit to use an external reference to change the main channel,whether voltage or current (see PAR. 3.4); ±10V reference produces output = ±Eo (rated) (Fixed gain= Eo (rated). Identical to CURR:MODE EXT.VOLT:MODE GAIN Configures the unit to use an external reference to provide a proportional outputvoltage.VOLT:MODE PROT - allows VOLT command to accept values up to the protection limits of thepower supply without generating an error. For example for a BOP 36-28MG in voltage mode, aftersending VOLT:MODE PROT, sending VOLT 36.4 would set the protection levels to 36.4 and mainchannel level to 36.Related Commands: LIST commands.

QUERY VOLT:MODE?Syntax: Short Form: [SOUR:]VOLT[:LEV]:MODE?Long Form: [SOURce:]VOLTage[:LEVel]:MODE?Return value: FIX, LIST, TRANS, EXT, or GAINDescription: Identifies active voltage mode. See PAR. B.95 for further details Related Commands: LIST com-mands. (See example, Figure B-5.)B.97 [SOURce:]VOLTage[:LEVel]:PROTect:BOTH COMMAND VOLT:PROT[:BOTH]Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT[:BOTH] Long Form: [SOURce:]VOLTage[:LEVel]:PROTect:[BOTH] where is between minimum (box) value (Figure 1-3) and 1% above rated (nominal) outputvoltage.Description: Establishes the both the positive and negative protection limits for voltage. If the protection limits arenot identical the unit automatically reduces the appropriate limit (see Figure B-9).B.98 [SOURce:]VOLTage[:LEVel]:PROTect[:BOTH]? QUERY VOLT:PROT[:BOTH]?Syntax: Short Form: [SOUR:]VOLT[:LEV]:PROT[:BOTH]?Long Form: [SOURce:]VOLTage[:LEVel]:PROTect[:BOTH]?Returns ,Description: Identifies the protection limits for voltage (positive, negative); maximum is 1% greater than rated out-put voltage.
