B.79 [SOURce:]VOLTage:PROTection:UNDer:STATE[:LEVel] COMMAND

VOLT:PROT:UND:STAT

Syntax:

Short Form: [SOUR:]VOLT:PROT:UND:STAT[:LEV]
Long Form: [SOURce:]VOLTage:PROTection:UNDer:STATe[:LEVel]
where = 1 (enabled) or 0 (disabled)

Description: Enables (1) or disables (0) the undervoltage protection level set using VOLT:PROT:UND. This

command saves having to change the protection level to some value outside of the operating range.

B.80 [SOURce:]VOLTage:PROTection:UNDer:STATE[:LEVel]? QUERY

VOLT:PROT:UND:STAT?

Syntax:

Short Form: [SOUR:]VOLT:PROT:UND:STAT[:LEV]?
Long Form: [SOURce:]VOLTage:PROTection:UNDer:STATe[:LEVel]?
Returns: = 1 (enabled) or 0 (disabled)

Description: Indicates whether the undervoltage protection level set using VOLT:PROT:UND is enabled (1)

or disabled (0).

B.81 [SOURce:]VOLTage:RANGe COMMAND

VOLT:RANG

Syntax:

Short Form: [SOURce:]VOLT:RANG Long Form: [SOURce:]VOLTage:RANGe
Where = 0, 1, 2, 3 or 4

Description: Controls the placement of the decimal point during remote interface readback of voltage, and

on the front panel VOLTS display when showing voltage. Display Ranges: 0 - Auto, 1 - 0.000, 2 -
00.00, 3 - 000.0, 4 - 0000.

B.82 [SOURce:]VOLTage:RANGe? QUERY

VOLT:RANG?

Syntax:

Short Form: [SOURce:]VOLT:RANG?

Long Form: [SOURce:]VOLTage:RANGe?

Returns = 0, 1, 2, 3 or 4

Description: Indicates the placement of the decimal point during remote interface readback of voltage, and

on the front panel VOLTS display when showing voltage. Display Ranges: 0 - Auto, 1 - 0.000, 2 -
00.00, 3 - 000.0, 4 - 0000.

B.83 STATus:CHANnel[:EVENt]? QUERY

STAT:CHAN?

Syntax:

Short Form: STAT:CHAN[:EVEN]?

Long Form: STATus:CHANnel[:EVENt]?

Returns: <16 bits> = the value of the Channel event register.

Description: Returns value of Channel event register. Each PFM within a chassis has three Channel registers

associated with it. Bits in the Event register are set whenever the associated condition occurs, and are
cleared only upon an explicit command, thus latching any conditions that occur. See Table B-2 for bit
assignments.

B.84 STATus:CHANnel:CONDition? QUERY

STAT:CHAN:COND?

Syntax:

Short Form: STAT:CHAN:COND?

Long Form: STATus:CHANnel:CONDition?

Returns: <16 bits> = the value of the Channel condition register.

Description: Returns the value of the Channel Condition Register. Each PFM within a chassis has three Chan-

nel registers associated with it. The Condition register reflects the instantaneous state of that PFM.
Bits in the Event register are set whenever the associated condition occurs, and are cleared only upon
an explicit command, thus latching any conditions that occur. See Table B-2 for bit assignments.
