Command Guidelines

Units of Measure

Units for measure-

ments

These are implemented such that a measurement query result will be

returned in the current GPIB unit.

Units for settings These are implemented such that if a unit is not sent along with the

setting value, then a default GPIB unit is used.

• For example, RFGenerator:AMPLitude1 assumes dBm and

RFGenerator:FREQuency assumes Hz. Ifa unit issent with the

setting, then this unit will be used. The GPIB unit may be

changed using the units commands described later.

• Each measurement or setting description defines the allowable

units for that field. When units are sent with a command, they

should not be quoted.

The complete allowable set of GPIB units that setting queries or

measurement queries may be returned in are:

• DB (dB), DBM (dBm), DBUV (dB micro-volt),

• DEG (degree), DIV (division),

• HZ (Hz), OHM (ohm), PCT (percent), PPM (parts-per-million),

• S (second), T (bit periods),

• V (volt), W (watts)

The complete allowable set of units that can be sent with setting

commands or units that can be displayed on the front panel are:

• DB (dB), DBM (dBm), DBMW (dB milli-watt), DBUV (dB micro-

volt),

• HZ (Hz), KHZ (kHz), MHZ (MHz), GHZ (GHz),

• T (bit periods), S (second), MS (milli-second), US (microsecond),

• V (volt), MV (millivolt), UV (microvolt),

• W (watts), MW (milliwatt),

• PCT (percent), PPM (parts-per-million),

• DEG (degree) DIV (division), OHM (ohm)
