Table 2-1. Numerical Data Formats

Data Form

Talking Formats

Digits with an implied decimal point assumed at the right of the least-significant digit. Examples: 273 0273

Digits with an explicit decimal point. Example: 273. .0273

Digits with an explicit decimal point and an exponent. Example: 2.73E+2 273.0E-2

Listening Formats

Extended format that includes <NR1>, <NR2> and <NR3>. Examples: 273 273. 2.73E2

Expanded decimal format that includes <NRf> and MIN 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 2-2. 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 1 0 or ON OFF may be sent with commands. Queries always return 1 or 0.

OUTPut OFF

CURRent:PROTection 1

String Data

Strings are used for both program (listening) and response (talking) data. String content is limited to the characters required for the link command parameters (see "Chapter 3 - Language Dictionary").

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.

Character Data

Character strings returned by query statements may take either of the following forms, depending on the length of the returned string:

<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.
