Display units:

Absolute: Watts or dBm

Relative: Percent or dB

Display resolution:

Resolution of 1.0, 0.1, 0.01 and 0.001

dB in log mode; one to four digits in

linear mode

Default resolution:

0.01 dB in log mode; three digits in

linear mode

Zero:

For performing internal and external

zeroing

Range:

Sensor-dependent, configurable in

1-kHz steps

2. Recording time for trace graphs may vary based on trace graph settings

Relative:

Displays all successive measure-

ments relative to the last referenced

value

Offset:

Allows power measurements to be

offset by –100 dB to +100 dB, con-

figurable in 0.001 dB increments, to

compensate for external loss or gain

Duty cycle:

Duty cycle values between 0.001% to

99.999% can be entered in increments

of 0.01% to display a pulse power

representation of measured power.

The following equation is used to

calculate the displayed pulse power

value: Pulse Power = Measured

Power/Duty Cycle

Limits:

High and low limits can be set in

the range between –150.00 dBm

to +230.000 dBm, in 0.001 dBm

increments

Preset default values:

Channel Offset (dB) = 0, Duty Cycle

Off, Frequency 50 MHz, AUTO

Average, AUTO Range, Free Run

Mode, dBm mode
