   Keysight (Agilent) 438A   Description / Specification:    
Keysight (Agilent) 438A Dual-Ch Digital RF Power Meter

The Agilent 438A power meter is a dual-channel power meter designed specifically for ATE systems. The compact front panel saves critical rack space, while the dual-channel design allows simple and accurate measurements of the ratio and difference of power levels from two separate sensors. This meter is compatible with the HP 8480 series of thermocouple and diode power sensors. Specifications. Frequency Range: 100 kHz to 110 GHz, sensor dependent. Power Range: –70 to +44 dBm (100 pW to 25 W), sensor dependent, uses HP 8480 series power sensors. Instrumentation Accuracy. Single Channel: ±0.5% (watt mode) or ±0.02 dB (dBm mode), Dual Channel: ±1% (watt mode) or ±0.04 dB (dBm mode). Zeroing: Automatic, ±0.5% of full scale on most sensitive range. Power Reference. Power Output: 1.00 mW. Factory set to ±0.7%, traceable to the U.S. National Institute Standards and Technology. Accuracy: ±1.2% worst case (±0.9% rss) for 1 year. Connector: Front panel type-N female (also rear panel Option 002). Options. Opt 002 Rear-Panel Sensor Connector (in parallel with front panel) and additional reference oscillator with rear-panel output. Opt 700 Internal MATE Programming. Opt 004 Deletes Power Sensor Cables.

*This is a Web introductory price for one calibration of the Keysight (Agilent) 438A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Harmonic
A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.
