Phase noise at an output frequency of 1 GHz is better than -106 dBc/Hz at an offset of 100 kHz from the carrier. Spurious emissions are typically lower than -70 dBc and harmonics less than -25 dBc.
The clean output signal combined with power levels to +13 dBm, controllable on 0.1 dB steps, make the ASG series of Miniature Signal Generators suitable for use in most RF theatres of application including test and measurement, communications systems and covert interception and countermeasures.
The ASG digital interface provides control options which include direct USB with convenient and clearly functional GUI plus input power derivation; and each unit also has the capability of being driven by RS232. Additionally, for both the 6 GHz version of the ASG Miniature Signal Generator and its 3 GHz sibling there is an option of Ethernet control thereby allowing totally remote and unattended operation in the field and picking up all the logistics and cost advantages.
Frequency stability is determined by an internal TCXO with +/-1 ppm maximum variation over the -20 to +50C operating temperature range but the Miniature Signal Generator can also be connected to an external reference of between 10 and 50 MHz where system stability tracking is required. With all this RF performance, digital connectivity and operational versatility the ASG design comes in a package just 21 x 72 x 100 mm and weighs less than 300 grams.
