AM, FM, analog modulation, and pulse modulation are supported up to 3.6 GHz and I/Q modulation and I/Q baseband output are supported to 6.5 GHz. The signal generator has phase noise of less than 116 dBc/Hz at a 20 kHz offset and an amplitude range of -130 dBm to +25 dBm with accuracy of less than 0.5 dB. The instruments have a 1 ppm internal clock, optional 5 ppb high-stability clock, and optional pulse modulation and pulse train generator. It has a user-defined pulse train generator, I/Q modulation and I/Q baseband output, 2U height with an available rack mount kit, and support for USB, Ethernet, and GPIB remote control and a SCPI command set.
