Agilent Technologies 6631B Table B-2. COMPatibility Commands, Compatibility Description Command

B - Compatibility Language

	Table B-2. COMPatibility Commands (continued)
Compatibility	Description
Command
UNMASK	These commands determine the conditions that will set bits in the

xxxfault register, allowing the operator to define the conditions that will be reported as fault Fault conditions can be enabled by sending the decimal equivalent of the total bit weight of all conditions to be enabled.

VOUT?	This command measures and returns the actual output voltage.
	Data Representation: SZZD.DD; (SZD.DDD for 6634B only)
VSET <n>	This command programs the output voltage. See Table 4-3 for the
	programming range of this command.
	Initial condition: 0 V

A = Alpha

D = Digit

S = Sign (blank for positive and – for negative)

Z = Digit with leading zeros output as spaces

Table B-3. COMPatibility Errors

NumberError String [Description/Explanation/Examples]

No error

No relay option present [A relay option command was sent with no relay option present.]

Addressed to talk and nothing to say [The unit was addressed to talk without first receiving a query.]

Header expected [A non-alpha character was received when a header was expected.]

Unrecognized header [The string of alpha characters received was not a valid command.]

Number expected [A non-numeric character was received when a number was expected.]

Number Syntax [The numeric character received did not represent a proper number.]

Number out of internal range [The number received was too large or small to be represented in internal format.]

Comma [A comma was not received where one was expected.]

Terminator expected [A valid terminator was not received where one was expected.]

Parameter Out [The number received exceeded the limits for its associated command.]

Voltage Programming Error [The programmed value exceeded the valid voltage limits.]

Current Programming Error [The programmed value exceeded the valid current limits.]

Overvoltage Programming Error [The programmed value exceeded the valid overvoltage limits.]

Delay Programming Error [The programmed value exceeded the valid delay limits.]

Mask Programming Error [The programmed value exceeded the fault mask limits.]

EEPROM Checksum [EEPROM failed, or a new uncalibrated EEPROM was installed.]
