Supplemental Characteristics

Power Reference

Frequency: 50 MHz nominal.
SWR: 1.05 maximum.
Connector: Type N (f), 50 ohms.

Measurement Speed

Three measurement speed modes, over the GPIB, are
available as shown, along with the typical maximum
measurement speed for each mode.

With the E4418B power meter:

Normal: 20 readings/second
x2: 40 readings/second
Fast: 200 readings/second

With the E4419B, the measurement speed is reduced, for
example, with both channels in FAST mode, the typical max­imum measurement speed is 100 readings/second.

Fast mode is for E-series sensors only.

Maximum measurement speed is obtained using binary out­put and in Free Run trigger mode.

Zero Drift of Sensors: Sensor dependent, refer to Table 2.
For E9300 sensors, refer to Table 12 for complete data.

Measurement Noise: Sensor dependent, refer to Table 2
and Table 3. For E9300 sensors, refer to Table 12.

Effects of Averaging on Noise: Averaging over 1 to 1024
readings is available for reducing noise. Table 2 provides the
Measurement Noise for a particular sensor with the number
of averages set at 16 (for Normal mode) and 32 (for x2
mode). Use the Noise Multiplier, for the appropriate mode
(Normal or x2) and number of averages, to determine the
total Measurement Noise value.

Example:

8481D Power Sensor, Normal mode, Number of
Averages = 4.

Measurement Noise calculation:

(<45 pW x 2.75) = <121 pW.

Table 2

1. Within 1 hour after zero set, at a constant temperature,after a 24-hour warm-up of the
power meter.

2. The number of averages at 16 for Normal mode and 32 for x2 mode, at a constant
temperature, measured over a one minute interval and two standard deviations. For
E-series sensors, the measurement noise is measured within the low range.
Refer to the relevant sensor manual for further information.

3. Specification applies to the Low Power Path, 15% to 75% relative humidity.

Power Meter Functions

Accessed by key entry: either
hardkeys, or softkey menu, and
programmable.

Zero: Zeros the meter. (Power refer­ence calibrator is switched off during
zeroing.)

Cal: Calibrates the meter using
internal (power reference calibrator)
or external source. Reference Cal
Factor settable from 1% to 150%, in

0.1% increments.

Frequency: Entered frequency range
is used to interpolate the calibration
factors table.

Range: 1 kHz to 999.9 GHz, settable in
1 kHz steps.

Cal Factor: Sets the Calibration
Factor for the meter. Range: 1% to
150%, in 0.1% increments.

Relative: Displays all successive
measurements relative to the last
displayed value.

Offset: Allows power measurements
to be offset by –100 dB to +100 dB,
settable in 0.001dB increments, to
compensate for external loss or gain.

Save/Recall: Store up to 10 instru­ment states via the Save/Recall menu.

dBm/W: Selectable units of either
Watts or dBm in absolute power;
or percent or dB for relative measure­ments.

Filter (averaging): Selectable from
1 to 1024. Auto-averaging provides
automatic noise compensation.

a peak power representation of meas­ured power. The following equation is
used to calculate the displayed peak
power value: Peak Power = Measured
Power/DutyCycle.

Sensor Cal Tables: Selects cal factor
versus frequency tables corresponding
to specified sensors ( 8480 series
