This article outlines the key differences between the Rohde & Schwarz CMU200 and the Agilent (now Keysight) 8960, both widely used instruments for testing GSM mobile phones and devices supporting other wireless standards.
Feature Comparison
The following table summarizes the differences in key features between the CMU200 and the 8960:
| Feature | R&S CMU200 | Agilent 8960 |
|---|---|---|
| Technologies Supported | Supports WCDMA, HSPA, GSM/GPRS/EDGE, AMPS, CDMA2000, Bluetooth | WCDMA, HSPA, EVDO, TD-SCDMA, GSM/GPRS/EGPRS, AMPS, CDMA2000 |
| RF Frequency Range Supported | 10 MHz to 2.7 GHz | 292 MHz to 2.7 GHz |
| Output Power Level | -130 dBm up to 13 dBm | -110 to 13 dBm |
| VSWR | Less than 1.2 for frequency 10 MHz to 2000 MHz range. | About 1.2:1 (for frequency range 400 to 2000 MHz) |
| Channel Power Accuracy | Varies between 0.6 to 1.5 dB based on RF frequency | +/- 1 dB |
| Interfaces | GPIB/LAN/USB | GPIB/LAN/USB |
| RF Vector Signal Generation & Analysis | Supported | Supported |
| RF/Conformance Tests | Supports various GSM measurements and GPRS tests (multi slot, AMR, Test mode A and Test mode B) for testing mobile. Supports call set up and call release features. | Used for RF parametric measurements, as network emulation, RF conformance test of mobile devices. Supports call set up and call release features. |
The CMU200 generally supports a wider range of technologies and a lower starting frequency for RF signal generation. The Agilent 8960 is geared towards network emulation and RF conformance testing.
