B.92 [SOURce:]VOLTage[:LEVel]:LIMit:NEGative COMMAND

VOLT:LIM:NEG

Syntax:

Short Form: [SOUR:]VOLT[:LEV]:LIM:NEG
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:NEGative
where is between zero and rated (nominal) output voltage

Description: Establishes the software limit for negative output voltage, i.e., sets the maximum value of

negative output voltage that the unit will be allowed to produce. Requires MEM:UPD (PAR. B.12) to
save for power up. See PAR. 3.5.2.2 and Figure 3-16 for special programming considerations.

B.93 [SOURce:]VOLTage[:LEVel]:LIMit:NEGative? QUERY

VOLT:LIM:NEG?

Syntax:

Short Form: [SOUR:]VOLT[:LEV]:LIM:NEG?
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:NEGative?

Description: Identifies the software limit value for negative output voltage specified by the user.

B.94 [SOURce:]VOLTage[:LEVel]:LIMit:POSitive COMMAND

VOLT:LIM:POS

Syntax:

Short Form: [SOUR:]VOLT[:LEV]:LIM:POS
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:POSitive
where is between zero and rated (nominal) output voltage

Description: Establishes the software limit for positive output voltage, i.e., sets the maximum value of pos-

itive output voltage that the unit will be allowed to produce. Requires MEM:UPD (PAR. B.12) to save
for power up. See PAR. 3.5.2.2 and Figure 3-16 for special programming considerations.

B.95 [SOURce:]VOLTage[:LEVel]:LIMit:POSitive? QUERY

VOLT:LIM:POS?

Syntax:

Short Form: [SOUR:]VOLT[:LEV]:LIM:POS?
Long Form: [SOURce:]VOLTage[:LEVel]:LIMit:POSitive?

Description: Identifies the software limit value for positive output voltage specified by the user.

B.96 [SOURce:]VOLTage:MODE COMMAND

VOLT:MODE

Syntax:

Description: Allows the user to execute or stop a list, to execute a transient, or to use an external reference.

The default mode is FIXed: the power supply executes commands 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). While

the 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 power

supply to settings in effect prior to running the list. If the list runs to completion, the settings of the last
step 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 the

current cycle.

VOLT:MODE TRAN nn causes the next VOLT: or CURR: command to produce a transient pulse of

nn Seconds duration, after which the voltage returns to original value. E.g., VOLT:25 sets the output to
25 volts, and VOLT:MODE TRAN 0.1 primes the unit for a transient of 0.1 Seconds. When VOLT:10 is
issued, 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 nn
exceeds 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 output voltage;

±10V reference produces output = ±Eo (rated) (Fixed gain = Eo (rated).

VOLT:MODE GAIN Configures the unit to use an external reference to provide a proportional output

voltage.

VOLT:MODE PROT - allows VOLT command to accept values up to the protection limits of the

power supply without generating an error. For example for a BOP 36-28MG in voltage mode, after
sending VOLT:MODE PROT, sending VOLT 36.4 would set the protection levels to 36.4 and main
channel level to 36.
