Instruction manual

3.7.3. NUMERIC DATA FIELD

Parameter values may be sent as an unsigned value with a decimal point or a decimal point

with an exponent. The phase value may be sent as a signed value.

The Decimal Point for numeric data values may be either sent or inferred. The two following

ASCII strings will represent 115 volts.

AMP115

AMP115.0

There may be any number of digits following the decimal point, not to exceed the 256 byte

DAM buffer, but only the Least Significant Digit (LSD) of resolution will be recognized. The

LSD for amplitude is tenths of volts. The LSD for frequency is either 0.01, 0.1 or 1 Hz for up

to 99.99, 99.99 Hz or 120.0 Hz respectively.

Any parameter's numeric value may be of a mixed form with a decimal point and exponent.

The exponent may be a numeric, with or without leading zeros, up to a value of ±63. The

following ASCII strings will represent 15 volts:

AMP1.15E2

AMP1.15E+2

AMP1.15E+02

AMP1150E-1

A positive exponent value is represented by either an ASCII "+" or an unsigned value.

3.7.4. PROGRAM HEADERS

A Program Header is a mnemonic of a series of three ASCII characters used to select a

function or identify the data it precedes. The header is an abbreviation of the program function

it identifies. The header may be followed by a header extension to separately program each

output (phase A, B or C) to different values. If an extension is not added to the header all

outputs will be programmed to the header's argument. See Table 3-12 for the definition of the

Program Headers and their related arguments.

Any header that is sent without an argument will cause the front display to show the

corresponding screen. Refer Figure 3-5 the for a summary of all possible command

sequences.
