Power Meter Functions
Accessed by key entry: either
hardkeys, or softkey menu, and
programmable.
Zero: Zeros the meter. (Power refer-
ence 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 instru-
ment states via the Save/Recall menu.
dBm/W: Selectable units of either
Watts or dBm in absolute power;
or percent or dB for relative measure-
ments.
Filter (averaging): Selectable from
1 to 1024. Auto-averaging provides
automatic noise compensation.
General Characteristics
Rear Panel Connectors
Recorder Outputs: Analog 0 to
1 Volt, 1 kohm output impedance, BNC
connector. E4419B recorder outputs are
dedicated to Channel A and Channel B.
Remote Input/Output: A TTL logic
level is output when the measurement
exceeds a predetermined limit. TTL
inputs are provided to initiate zero and
calibration cycles. RJ-45 series shielded
modular jack assembly connector. TTL
Output: high =4.8V max; low = 0.2V max
TTL
Input: high = 3.5V min, 5V max;
low = 1V max, -0.3V min.
GPIB: Allows communication with an
external controller.
RS-232/442: Allows communication
with an external RS-232 or RS-422 con-
troller. Male/Plug 9 position D-subminia-
ture connector
Ground: Binding post, accepts 4 mm
plug or bare-wire connection.
Line Power
Input Voltage Range: 85 to 264 VAC,
automatic selection.
Input Frequency Range: 50 to 440 Hz.
Power Requirement: approximately 50
VA (14 Watts) for E4418B and E4419B.
Duty Cycle: Duty cycle values
between 0.001% to 99.999%, in 0.001%
increments, can be entered to display
a peak power representation of meas-
ured 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
only).
Limits: High and low limits can be set
in the range –150.000 dBm to +230.000
dBm, in 0.001 dBm increments.
Preset Default Values: dBm mode,
Rel Off, Power Reference Off, Duty
Cycle Off, Offset Off, Frequency
50 MHz, AUTO Average, Free Run,
AUTO range (for E-series sensors).
Display: Selectable single and split
screen formats are available. A
quasi-analog display is available for
peaking measurements. The dual chan-
nel power meter can simultaneously
display any two configurations of A, B,
A/B, B/A, A-B, B-A and Relative.
