Descrizione del prodotto

The Signal Analyzer MS2690A/MS2691A/MS2692A(MS269xA) has the excellent general level accuracy, dynamic range and performance of a high-end spectrum analyzer. Its easy operability and built-in functions are perfect for tests of Tx characteristics. Not only can it capture wideband signals but FFT technology supports multifunction signal analyses in both the time and frequency domains. Behavior in the time domain that cannot be handled by a sweep type spectrum analyzer can be checked in the frequency domain. A wide frequency can be analyzed using sweep type spectrum  analysis functions while detailed signal analysis of a specific frequency band is supported too. Moreover, the built-in signal generator function outputs both continuous wave (CW) and modulated signals for use as a reference signal source when testing Tx characteristics of parts and as a signal source for evaluating Rx characteristics.

Wireless communications are tending toward use of higher frequencies above 3 GHz and wider bandwidths. However, general-purpose spectrum analyzers suffer from a degraded noise floor above 3 GHz due to the 3-GHz baseband, so they cannot be used to verify the true product performance. Because the MS269xA baseband can be extended up to 6 GHz it offers excellent level accuracy and modulation precision at frequencies from 50 Hz to 6 GHz. Adding the full line of versatile analysis software options eliminates the need for an external PC at wireless modulation analysis.

Moreover, installing a preselector bypass option (MS2692A-067) enables use of the signal analyzer and modulation analysis functions up to 26.5 GHz (MS2692A). Waveform creation software generates modulation signal patterns for all common wireless technologies to output signals for the vector signal generator function. The high-performance, multi-function MS269xA Signal Analyzer supports better analysis than more expensive standalone spectrum analyzers.


Basic Performance/Functions

Frequency Range

MS2691A: 50 Hz to 13.5 GHz

Total Level Accuracy: ±0.3 dB (typ.)

The Absolute Amplitude Accuracy specification described in

catalogs of other spectrum analyzers ignores the important

frequency characteristics, linearity, and attenuator switching

errors. The MS269xA calibration technology supports excellent

level accuracy over the wide frequency range from 50 Hz to 6 GHz

even under measurement conditions including the above three


Dynamic Range*1: 177 dB

TOI*2: ≥+22 dBm

DANL*3: –155 dBm/Hz

Improved Level Linearity

Internal Reference Oscillator

Pre-installed Reference Oscillator

Aging Rate: ±1 × 10–8/day

Start-up Characteristics: ±5 × 10–8 (5 minutes after power-on)

Rubidium Reference Oscillator (MS269xA-001)
