The Function Generator (CM1120-A) is a highly versatile, all-purpose signal source which is equally at home on the bench or in automated test systems. It combines synthesizer, sweep generator, and arbitrary waveform function in one compact unit. In addition to the 5 standard waveforms, "self-constructed" signals can be generated using the arbitrary function with 14-bit resolution, 80MSa/s sampling rates. Data entry, readout, and editing is possible via external interface, which also allows the transfer of waveform data stored in digital scopes. All arbitrary waveform data is stored in a non-volatile memory for quick recall until the data is reprogrammed.

Another feature of the CM1120-A is the integrated sweep generator with two frequency ranges. Sweep rate and start and stop frequencies are exceptionally quick and easy to set. Separate inputs are provided for external amplitude modulation, trigger/burst, and gate.

The frequency range of sine and square waves is 10mHz to 20MHz.

The range of the other waveforms is limited due to their digital generation.

Low harmonic Distortion, low aberration, and fast rise and fall times (<10ns) underscore the excellent overall performance of the CM1120-A.

Frequencies are indicated on a bright, 5-digit LED-display with a resolution of up to 10mHz. DC-offset is adjustable up to ± 10V. The highest available output voltage for all waveforms is 20Vpp O.C. or 10Vpp into 50 Ω . The signal output is short circuit proof and protected against a maximum of ± 15V of external voltage.

In addition to its versatility, the CM1120-A offers remarkable comfort and simplicity of operation. All variable parameters are quickly and precisely adjustable by means of the center dial. The bright display and the clearly arranged front panel design allow the user to be informed of instrument status and all other important parameters at a glance.
