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 increments of 0.1%.
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 0.001-dB 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.
Dimensions
The following dimensions exclude front
and rear protrusions:
212.6 mm W x 88.5 mm H x 348.3 mm D
(8.5 in x 3.5 in x 13.7 in)
Weight
E4418B: 4.0 kg (8.8 lb) net, 7.9 kg (17.4
lb) shipping
E4419B: 4.1 kg (9.0 lb) net, 8.0 kg (17.6
lb) shipping
Rear panel connectors
Recorder outputs: Analog 0 to
1-Volt, 1-k 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 = 4.8 V max; low = 0.2 V
max TTL
Input: high = 3.5 V min, 5 V max; low =
1 V max, –0.3 V min.
GPIB: Allows communication with an
external controller.
RS-232/422: Allows communication
with an external RS-232/422 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 W)
Duty cycle: Duty cycle values between
0.001% to 99.999%, in increments of
0.001%, 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/duty cycle.
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 dBm to +230 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 and N8480 Series sensors).
Display: Selectable single and split
screen formats are available. Aquasi-
analog display is available for peaking
measurements. The dual-channel power
meter can simultaneously display any
two configurations of A, B, A/B, B/A,
A-B, B-A and relative.
