Absolute Power Measurement Accuracy: The absolute power
measurement accuracy is determined by a number of factors
including calibrator accuracy, noise, sensor calibration factor
error, and the mismatch uncertainty between sensor and device
under test.
Calibrator: Provides a 50 MHz calibration signal at 51 very
accurately controlled levels from +20 to -30 dBm to dynamically
linearize the sensors.
Calibrator Frequency: 50 MHz nominal
Calibrator Connector: Type-N (f) precision connector, 50 Ω.
Settability: The 1.00 mW level in the power sweep is factory set
to ±0.7% traceable to the National Institute of Standards and
Technology (NIST).
Accuracy: ±1.2% worst case for one year, over temperature
range 15°C to 35°C.
Calibrator VSWR: < 1.05:1 (Return Loss > 33 dB)
Instrument plus Power Sensor Linearity:
Standard Sensors, CW Mode:
±0.02 dB (±0.5%) over any 20 dB range from +16 to -70 dBm
±0.02 dB + (+0 dB, -0.05 dB/dB) from +16 to +20 dBm
±0.04 dB (±1.0%) from +16 to -70 dBm
Standard Sensors, Swept Mode:
±0.03 dB (±0.7%) over any 20 dB range from +16 to -70 dBm
±0.03 dB + (+0 dB, -0.05 dB/dB) from +16 to +20 dBm
±0.06 dB (±1.4%) from +16 to -70 dBm
Low VSWR Sensors:
-64 to +20 dBm: Same as for Standard Sensors.
+20 to +30 dBm: Same as for Standard Sensors, plus an
additional ±0.13 dB (typical).
High Power Sensors:
-60 to +20 dBm: Same as for Standard Sensors.
+20 to +30 dBm: Same as for Standard Sensors, plus an
additional ±0.13 dB (typical).
True RMS Sensors, CW Mode:
±0.02 dB (±0.5%) over any 20 dB range from +20 to -30 dBm
±0.04 dB (±1.0%) from +20 to -30 dBm
True RMS Sensors, Swept Mode:
±0.03 dB (±0.7%) over any 20 dB range from +20 to -30 dBm
±0.06 dB (±1.4%) from +20 to -30 dBm
Temperature Coefficient of Linearity: < 0.3%/°C temperature
change after calibration
Zeroing Accuracy, (CW Mode, Averaging Factor = 32):
Zero set: ±50 pW
Zero drift: < ±200 pW (typical) in 1 hour at constant
temperature after at 24 hour warm-up.
Zeroing Accuracy, (Swept Mode, Averaging Factor = 32):
Zero set: ±50 pW (AC Detection), ±800 pW (DC Detection)
Zero drift: 2 nW (DC detection), typical, in 1 hour at constant
temperature after 24 hour warm-up. Zero drift not applicable
in AC detection.
Noise Uncertainty: < 50 pW, typical, at constant temperature,
measured over a 1 minute interval, two standard deviations.
Cal Factor Correction: Manual or automatic correction to power
readings to compensate for frequency response variations of the
power sensors and bridges.
Manual: Cal Factor, Cal Frequency, Off
Automatic: Sweeper
