RF signal generators are high-spec, low cost, says RS Components
Compact, low-cost, high-spec RF signal generators from Aim-TTi are now available from RS Components. The TGR2050 series is aimed at industrial electronics design, test and service engineers. Models combines high-frequency accuracy and stability with low phase noise, a wide output amplitude range and digital modulation capabilities.
There are two models in the Aim-TTi TGR2050 series, the TGR2051 and TGR2053. Output frequency ranges are from 150kHz to 1.5GHz and 3GHz, respectively. Both models offer 1ppm frequency accuracy, frequency stability to within 1ppm drift over the first year, and phase noise less than –117dBc/Hz (typical) at 1GHz output and 10kHz offset. Output amplitude range is from -127dBm to +13dBm, with setting resolution of 0.1dBm.
To test a wide range of input conditions quickly and efficiently, the TGR2051 and TGR2053 can perform fast amplitude and frequency sweeps with five milliseconds sweep settling time. Formula specifics include start and stop values and dwell time following ‘sync’ at each point. Sweeps can be run in either direction, with linear or logarithmic spacing. Alternatively, a list mode can be used to analyse responses at set frequencies and amplitude for testing at known problem frequencies.
Internal or external analogue modulations (AM, FM and PM) are included, with a range of complex digital modulations. For example, the TGR-U01 option adds FSK, GFSK, MSK, GMSK, HMSK, 3FSK, 4FSK, PSK, ASK and OOK, with built-in NRZ patterns including square wave and 7-, 9-, 11- or 15-bit PRBS. Advanced filtering options include Gaussian, raised cosine, root raised cosine and half sine. External digital modulation signals can be applied via a MOD in/out on the rear panel.
The TGR2051 and TGR2053 have an intuitive user interface operated via an integrated 4.3-inch colour touchscreen. It displays key information alongside readings. The instruments are SCPI-compatible and can be programmed via USB, LAN (LXI) and, optionally, GPIB.
TGR2050 Series signal generators are packaged in a small-footprint (2U half rack) case and weigh 3kg. they are compatible with previous Aim-TTi RF generators and can be integrated into existing systems.
The TGR2050 Series of signal generators is shipping now from RS in the EMEA and Asia Pacific regions.
