The Agilent N9310A is an RF signal generator that produces continuous-wave and modulated signals across a frequency range of 9 kHz to 3.0 GHz. It sets frequency with 0.1 Hz resolution and output power from -127 to +13 dBm (with +20 dBm settable), combining a built-in 6.5-inch 640 x 480 display, front-panel control, and USB connectivity in a single benchtop instrument.

A signal generator supplies the known, controllable stimulus a device under test needs in order to produce a measurable response, which is why generators are paired with oscilloscopes, analyzers, and automated test setups. The N9310A delivers that stimulus with amplitude, frequency, phase, and pulse modulation, and—when equipped with Option 001—external I/Q modulation characterized by 3% typical QPSK EVM and 1.2 degree rms typical GMSK phase error for vector and digital-format signals.

ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the equipment you order is on hand rather than sourced on demand. Every pre-owned unit is supported by our team directly: used units are inspected and functionally verified in-house before they ship, while new units ship factory-sealed exactly as received from the manufacturer.

## Brand Heritage

This instrument carries Agilent Technologies branding. Agilent was established in 1999 as a spin-off of Hewlett-Packard's test and measurement business; in 2014, Agilent's electronic measurement division was spun off again to form Keysight Technologies.
