5-9. Parameter Syntax Rules

Many of the remote commands require parameters, which must be used properly to avoid

command errors. When a command error occurs, bit CME (5) in the Event Status Enable

1. When a command has more than one parameter, the parameters must be separated by

commas. For example: “OUT 1 V, 100 HZ.”

2. Numeric parameters may have up to 255 significant figures and their exponents may

range from -32000 to +32000. The useful range for calibrator programming is ± 2.2

E-308 to ± 1.8 E308.

3. Including too many parameters causes a command error.

4. Null parameters cause a command error (e.g., the adjacent commas in “CLOCK

133700, , 071787”).

5. Expressions, for example “(4+2*13)”, are not allowed as parameters.

Units accepted in command parameters and used in responses are:

• HZ (frequency, hertz)

• MHZ (frequency, megahertz)

• V (voltage, volts)

• A (current, amperes)

• OHM (resistance, ohms)

• MOHM (resistance, megohms)

• DB (decibels)

• DBM (decibels referenced to 1 milliwatt for ac voltage amplitude)

• PCT (percent)

• PPM (parts per million)

Multipliers accepted in command parameters are:

• MA (mega, or unit x 1,000,000)

• K (kilo, or unit x 1,000)

• M (milli, or unit /1,000; except MOHM and MHZ)

• U (micro, or unit /1,000,000)

Some examples of allowed unit and multiplier combinations are:

• “MOHM” and “MAOHM” are both interpreted as megohms

• “MHZ”and “MAHZ” are both interpreted as megahertz

• “MV” is interpreted as millivolts

• “MAV” is interpreted as megavolts

• “MA” is interpreted as milliamperes
