Aeroflex announced the addition of an internal pulse generator option for the 2023A Series signal generator. This new option greatly facilitates testing in EMC and radar applications by providing an integrated solution that removes the need for an external pulse generator and simplifies test procedures. In addition, Aeroflex has enhanced the instrument’s internal modulation oscillator to extend its stimulus capabilities.

The new pulse generator option, with a minimum pulse width of 50 ns and maximum PRF of 10 MHz, works with both pulse modulators available for the 2023A Series signal generators. The standard pulse modulator provides an on/off ratio of > 45 dB with rise/fall times of < 10 ms and operates over the carrier frequency range from 32 MHz to the instrument’s maximum frequency. The instrument’s fast pulse modulator option, which is specified from 100 kHz to the instrument’s maximum frequency, operates down to 9 kHz, making it ideal for EMC applications. The fast pulse modulator provides an on/off ratio of > 80 dB with rise/fall times of typically 10 ns, suiting the requirements of radar applications. Adding the pulse generator option makes the 2023A Series signal generator a complete solution for both the EMC and radar applications.

Aeroflex has also enhanced the 2023A Series’ standard internal modulation oscillator, offering modulating frequencies up to 100 kHz and providing a “function generator” mode in which the user can control LF output level as well as frequency. Effectively creating two instruments in one, the function generator mode extends the 2023A Series ability to provide stimulus for audio devices and sub-assemblies while simultaneously generating an unmodulated RF carrier.
