AUSTIN, Texas, 19 Aug. 2009. Aeroflex Test Solutions in Plainview, N.Y., is introducing an internal pulse generator option for the 2023A series signal generator for test and measurement in electromagnetic compatibility (EMC) and radar systems.

The radar test and EMC test pulse RF signal generator can remove the need for an external radar signal pulse generator in commercial and military test applications. Aeroflex also has enhanced the instrument's internal modulation oscillator to extend its stimulus capabilities. The company made the announcement this week at the IEEE EMC Symposium 2009 in Austin, Texas.

The pulse generator option, with a minimum pulse width of 50 nanoseconds 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 microseconds 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 for EMC applications. The fast pulse modulator provides an on/off ratio of >80 dB with rise/fall times of typically 10 nanoseconds.

Aeroflex has also enhanced the 2023A's standard internal modulation oscillator, offering modulating frequencies as high as 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.
