The Signal Analyzer MS2830A-044/045 includes a spectrum analyzer function for measuring up to 325 GHz using an external mixer based on the 26.5 GHz/43 GHz upper frequency limit. It supports measurements of Tx characteristics, including adjacent channel leakage power, spectrum mask, and frequency counter, as well as spurious measurements requiring a wide dynamic range.
Installing the 10/31.25/62.5/125 MHz analysis bandwidth option adds signal analyzer functions for checking phenomena that are hard to check using a spectrum analyzer, such as frequency vs. time, phase vs. time, spectrogram, and CCDF. In addition, optional measurement software supports modulation analysis. Moreover, installing a preselector bypass option enables use of the signal analyzer and modulation analysis functions up to 26.5 GHz/43 GHz. Finally, it can be customized to support a range of application-specific measurements.
- Installing a microwave-band preamp supports measurement of weaker signals.
- Using the 1st local signal output as an external mixer supports measurement of high-frequency signals up to 325 GHz.
- Using the 1st IF signal output as a down converter supports analysis in combination with external equipment.

■Signal Analyzer Function (MS2830A-006, 005/009, 077, 078)
|Analysis band width
||10, 31.25, 62.5*, 125* MHz（Opt.006, 005/009**, 077, 078）
**Opt.005: For MS2830A-044, Opt.009: For MS2830A-045
|*An image response is received when setting the bandwidth to more than 31.25 MHz.
This can be used when not inputting a signal frequency outside the MS2830A analysis bandwidth (125 MHz max.).
The MS2690A/91A/92A is recommended for other measurement purposes.
