SCPI Data Formats

All data programmed to or returned from the power supply is ASCII. The data may be numerical or character string.

Numerical Data

Table 6-1 and Table 6-2 summarize the numerical formats.

			Table 6-1. Numerical Data Formats
Symbol						Data Form
					Talking Formats
<NR1>		Digits with an implied decimal point assumed at the right of the least-significant
		digit. Examples: 273		0273
<NR2>		Digits with an explicit decimal point. Example: 273. .0273
<NR3>		Digits with an explicit decimal point and an exponent. Example: 2.73E+2 273.0E-2
					Listening Formats
<NRf>		Extended format that includes <NR1>, <NR2> and <NR3>. Examples: 273 273.
		2.73E2
<NRf+>		Expanded decimal format that includes <NRf>, MIN and MAX. Examples: 273
		273. 2.73E2 MAX. MIN and MAX are the minimum and maximum limit values
		that are implicit in the range specification for the parameter.
			Table 6-2. Suffixes and Multipliers
	Class		Suffix		Unit		Unit with Multiplier
	Current		A		Ampere		MA (milliampere)
	Amplitude		V		Volt		MV (millivolt)
	Time		S		second		MS (millisecond)
			Common Multipliers
			lE3		K		kilo
			1E-3		M		milli
			1E-6		U		micro

Boolean Data

Either form {10} or {ONOFF} may be sent with commands. Queries always return 1 or 0.

OUTPut OFF

CURRent:PROTection 1

Character Data

For query statements, character strings may be returned in either of the forms shown in Table 6-3, depending on the length of the returned string.

	Table 6-3. Character Data Formats
<CRD>	Character Response Data. Permits the return of character strings.
<AARD>	Arbitrary ASCII Response Data. Permits the return of undelimited 7-bit ASCII. This data type has
	an implied message terminator.
Note:	The IEEE 488.2 format for a string parameter requires that the string be enclosed within either single
	(’ ’) or double (" ") quotes. Be certain that your program statements comply with this requirement.
