What are the differences between the Agilent 8903A, 8903B and 8903E?
The Agilent 8903B is the replacement for the Agilent 8903A. Here are the differences in the Agilent 8903B:
1. True Balanced Input to the Analyzer
2. Front Panel Switchable Detector, rms-to-Average
3. Quasi-Peak Detector, Accessible by Special Function
4. Lower Noise in the Analyzer Portion
5. Switchable Impedance, 50-600 Ohms, by Special Function
6. Voltage Measurements in dBm into 600 Ohms
7. Choice of Two Bandpass Filters from a Menu of 6 (8903A had Options 010 and 051)
The 8903E is simply the analyzer portion of the instrument; no source included. It has the same specifications as the analyzer portion of the 8903B. Not having a source, it cannot do signal to noise ratio; it has a special "notch-lock" function to enable measurement of SINAD and distortion.
Refer to Filer Options for additional information. Filter options are the same for the 8903B and 8903E:
