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
measurements.
Filter (averaging): Selectable from
1 to 1024. Auto-averaging provides
automatic noise compensation.
Duty cycle: Duty cycle valuesbetween
0.001% to 99.999%, in 0.001% incre-
ments, can be entered to display
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 correspond-
ing 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
channel power meter can simultane-
ously display any two configurations
of A, B, A/B, B/A, A-B, B-A and
relative.
General characteristics
Rear panel connectors
Recorder outputs: Analog 0 to
1 Volt, 1 k
Ω
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 measure-
ment exceeds a predetermined limit.
TTL inputs are provided to initiate
zero and calibration cycles. RJ-45
series shielded modular jack assem-
bly 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
controller. Male/plug 9 position
D-subminiature 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.
