The 2390A series of spectrum analyzers from IFR combine exceptional performance with excellent value for money. There are three instruments in the range:-
Frequency Accuracy
All three instruments are fully synthesized to give accurate frequency measurements. Even on wide spans the 2390A series gives precise frequency measurements and an integral frequency counter enables the measurement of individual signals to 1 Hz resolution. Fundamental mixing to 12 GHz enables the microwave versions to reach their maximum frequency in only two harmonic sweeps. This gives excellent sensitivity and accuracy right up to 26.5 GHz.
Narrow Resolution
The 2390A series all have resolution bandwidths down to 3 Hz. Narrow resolution bandwidths provide the ability to resolve closely spaced signals or sidebands.
The 3 Hz filter is also used for close in signal analysis, for example it can be used to identify 50 or 60 Hz power line sidebands on oscillators. The average displayed noise level when using a 3 Hz filter is less than -135 dBm at 2.9 GHz and below -125 dBm at 26.5 GHz. This makes 2390A series suitable for locating and identifying low level spurious and harmonic signals.
Wideband Filters for Spread Spectrum and Pulsed Signals
When analyzing signals with wide spectrum bandwidths such as digitally modulated carriers or pulsed radar, the resolution bandwidth of the spectrum analyzer can limit the measurement. The 2390A series have 10 MHz and 30 MHz bandwidth filters. These give the best available characterization of wideband signals and have an impulse bandwidth >5 MHz. In zero span mode a minimum sweep time of 200 ns/div makes displaying radar pulses precise and straightforward.
AM and FM Receiver Modes
The 2390A series features built-in receivers for both AM and FM signals. Modulation detection can be set to narrowband or wideband mode. For an FM transmission a modulation scale of 1 kHz to 5 MHz per division allows direct
