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. If a unit is sent 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)
