Signal generator

27 April 2011 Test & Measurement

Newly developed by Hittite is the HMC-T2220, a 10 MHz to 20 GHz synthesised signal generator which provides high output power, low harmonic levels and broad frequency range. Ideal for use in automated test and measurement environments, research and development laboratories, the instrument is compact and lightweight, and delivers up to +28 dBm of CW output power in 0,1 dB steps over a 60 dB dynamic range.

Harmonic rejection is better than -30 dBc and spurious products are better than

-57 dBc across the entire bandwidth. Phase noise is -99 dBc/Hz @ 100 kHz offset at 10 GHz with insignificant deviation over the temperature range of 0°C to

+35°C. The broad frequency range of 10 MHz to 20 GHz covers all major communication bands with frequency resolution of 1 Hz and fast switching speed of 300 μs.

Built on a foundation of Hittite’s high-quality MMICs, the signal generator features multiple interfaces (USB, GPIB and Ethernet) and control software ensuring carefree integration within multiple test environments. An installation disk that accompanies each unit includes all of the drivers (LabView, C) required to remotely control the device, as well as a user friendly GUI interface compatible with Windows XP, Windows Vista and Windows 7 operating systems.

User control is facilitated via pull-down menus that allow programming of single or swept modes in frequency and/or power. Integration of multiple units within a production test environment is straightforward. Furthermore, to facilitate integration into existing HMC-T2100 applications, the T2220 has a T2100 compatibility mode. In this mode, the T2220 identifies itself as a T2100 so that the T2100 USB drivers will work for a T2220. The T2220 frequency resolution, maximum and minimum power values and minimum sweep dwell time also change to match the T2100.
