Sweep function synthesiser

Anritsu has introduced a full suite of analog modulation and sweep options for its MG3690A series, a family of signal generators.

The addition of frequency, phase, pulse and amplitude modulation capabilities makes the series suitable for applications ranging from component manufacturing to laboratory signal simulation.

All four modulation options can be driven internally or externally via low frequency and pulse generators. By offering each modulation capability separately, users can configure the synthesiser for existing needs while also having an upgrade path as requirements expand.

The synthesisers can be configured for individual analysis - such as AM, FM/FM, PM, external/internal or analog sweep - or can be fully loaded to conduct all these measurements.

The instrument series is complemented by a performance down to 10 Hz offset. The signal generators are also claimed to produce the industry's best pulse performance, 1 ms at <2 GHz and 100 ns at >2 GHz.

All models achieve frequency resolution of 0.01 Hz over the full frequency range, with a variable phase offset that can be adjusted in 0.1 increments.

Six models covering 0.1 Hz to 65 GHz are available in the series. External waveguide multipliers that extend the frequency range to >110 GHz are also available. For vector modulation applications, an IF input that up-converts an external IQ-modulated IF signal to 40 GHz is available.

The models in the series can act as CW sources of single RF and microwave frequencies or as analog or digitally swept sources, sweeping either frequency or power, or both. As a CW source, the generators feature up to 20 independent markers to set independent CW frequencies.
