User`s guide

When using an E-series sensor in 438A language,

the FR (frequency) command will be accepted.

The syntax for this command is shown below.

Note: Sending this command when the active entry

channel is connected to an 8480 series sensor will

cause a syntax error.

The Agilent E-Series sensors have an upper and

lower range and are affected by the ranging com-

mands as detailed below.

• RA (auto range): The EPM series power meter

selects the most suitable range and this will

be reported in the status message range fields

for the attached sensor(s) (11 = lower range

and 12 = upper range).

• RH (range hold): The EPM series power meter will

hold on the current range irrespective of input

level and the status message range fields for the

attached sensor(s) will reflect this (01 = lower

range and 02 = upper range). The front panel

display will indicate that range hold is in effect.

• RM (manual range selection): The EPM series power

meter will select the lower range for RM1EN and

the upper range for RM2EN (RM3EN, RM4EN and

RM5EN are accepted and also select the upper

range). The status message range fields for

attached sensor(s) will reflect the range selected

(01 = lower range and 02 = upper range). The

front panel display will indicate that range hold

is in effect.

When calibrating an Agilent 8480 series sensor

using the power meter’s reference oscillator, an

error is returned if the sensor is not connected to

the power reference. This connection test does not

apply to E-series sensors.
