IFR / Marconi 2023B

The Marconi 2023B signal generator (IFR 2023B / 03) is portable and lightweight, offering carrier frequency 9 kHz to 2.05 GHz with a wide choice of modulation modes. The signal generator is suitable for a wide range of applications in laboratory, production, and maintenance environments. The GPIB facility allows the unit to be included in ATE systems for faster manufacturing throughput. An RS-232 interface is provided with a command set in common with the GPIB to simplify remote control of the signal generator in basic test systems or via a modem.

Amplitude and Pulse Modulation

Amplitude modulation with a 1 dB band-width of 30 kHz and modulation depths of up to 99.9% with a resolution of 0.1% ensures the generator is suitable for testing AM systems and undertaking EMC immunity measurements. The standard pulse modulation facility has an on/off ratio of better than 40 dB and a rise/fall time of less than 10 μs enabling characterization of TDMA or TDD bursts in RF amplifiers and modules. The internal square wave modulation source may be used to self pulse modulate the generator for use in EMI applications.

Frequency and Phase Modulation

With a 1 dB FM bandwidth of 275 kHz and a deviation range of 0 to 12.8 MHz, the 2023A/B and 2025 signal generators offer a wide range frequency modulation capability. AC or DC coupled FM can be selected with very low carrier frequency error and drift in the DC coupled mode ideal for testing paging and DCS (Digitally Coded Squelch) equipment accurately. The phase modulation facility is ideal for testing narrow band analog radios with a deviation range of 0 to 10 radians and a 3 dB bandwidth up to 10 kHz.
