Anritsu Co. introduces the MG3740A analog signal generator that outputs AM/FM/ΦM test signals for evaluation of narrowband analog radio equipment used in public safety networks and private commercial networks. Featuring best-in-class Single Side Band (SSB) phase noise performance and high-purity test signal output, the MG3740A is well suited for designers and manufacturers of public safety/commercial radio equipment and components, such as amplifiers and mixers.

Excellent -140 dBc/Hz SSB phase noise optimizes the test signals outputted from the MG3740A, allowing engineers to conduct highly accurate evaluations of narrowband analog radio equipment and components. Featuring level accuracy of ±0.5 dB over a wide level range of -110 to +17 dBm, the MG3740A allows for accurate tests of radio Rx sensitivity and amplifier distortion characteristics.

The MG3740A can be configured with an option that outputs digital modulations. With the option, the MG3740A can be used as a test signal source for dual-mode radio equipment supporting both analog and digital communications. The option also provides a cost-efficient and convenient method to meet future test needs when the conversion to full digital radio is completed. 

Additionally, the MG3740A can be configured with two sets of test signal output ports, eliminating the need for separate signal generators, reducing costs and saving space. With the option, the MG3740A can support both the wanted and interference waveform tests required by analog radio standards.
