Tektronix's TSG4100A Series of RF Vector Signal Generators with true DC to 2 GHz, 4 GHz, or 6 GHz, and up to 200 MHz modulation bandwidth, support both analog and vector signal generation. The series comes standard with analog modulation.
The VSG25A is a vector signal generator from Signal Hound featuring a 12-bit I/Q baseband waveform generator that is designed to easily generate analog, digital, and arbitrary waveforms. With the ability to be clocked at any frequency from 54 kHz to 180 MHz, and with an operating frequency range of 100 MHz to 2.5 GHz, this device also includes a 4096 x 16 bit pattern buffer for built-in or custom modulation.
This series of ultra-low noise signal sources features exceptionally low phase noise, supplementary output at oscillator frequency, and a wide range of output frequencies and multiplication ratios. They provide a range of high-performance building blocks between 200 MHz and 3 GHz.
As its model number implies, the 745-20C-T is a digital delay generator with 20 channels in one unit. It features a 100 ps time resolution (standard, with an optional 250 fs time resolution), 5 ps jitter (internal trigger), a 25 ps jitter (external trigger), 1 ns output rise times, and more.
This ultra-compact RF signal generator is ideal for EMC/EMI applications and for use as a general purpose RF source. It comes in a compact and rugged enclosure and covers the 9 kHz to 3.0 GHz frequency range.
Berkeley Nucleonics' new Model 855 series is a phase coherent, multi-output, fast switching, and low phase noise signal generator operating within the 10 MHz to 6.2, 12.5, or 20.0 GHz range, ideally used for applications where accurate signal quality and wide output power are required.
