Low-cost DDS function generator operates to 10 MHz

The TG1000 can generate frequencies between 0.001 Hz and 10 MHz to six digits of resolution at amplitudes between 5 mV and 20 V peak-to-peak EMF. Source impedance is switchable between 50 and 600 ohms.

Frequencies can be set directly in mHz, Hz, kHz or MHz or as period in time units using the numeric keyboard or the spin wheel. Amplitudes can be set in mV, V or dBm.

The TG1000 is a fully digitally controlled generator in which all functions including wave shape, frequency, amplitude, offset and modulation can be controlled from the internal set-up memories. This makes it particularly suitable for repetitive test applications.

The generator incorporates fully phase-continuous sweep, linear or logarithmic, with sweep times variable between 50 ms and 1000 s. The sweep trigger source can be internal or external, and a sweep marker is provided. Other modulation modes include AM, gated, FSK and tone-switch using a table of up to 16 frequencies.

The TG1000 is housed in a 2U high casing with built-in tilt stand which, although primarily intended for benchtop use, can also be rack-mounted.
