KEYSIGHT U2761A 20 MHz USB Modular Function Generator

The Keysight U2761A is a 20 MHz USB modular function generator with arbitrary waveform and pulse generation capability. It can operate as a standalone or modular unit when used together with the U2781A USB modular product chassis. The U2761A adopts the latest direct digital synthesis (DSS) technology that digitally creates arbitrary waveforms and frequencies from a single fixed frequency source. DDS offers the precision of digitally controlled logic - increasing the stability while reducing the complexity of the generator. This generates an accurately stable output signal for clean, low distortion sine wave and square wave coupled with fast rise and fall time up to 20 MHz and linear ramp waves up to 200 kHz. The U2761A is able to generate pulses from 500 µHz to 5 MHz. Designed with variable period, pulse width and amplitude parameters, the U2761A is ideal for a wide range of applications demanding flexible pulse width signals. With internal AM, FM, PM, ASK, FSK and PSK modulation it is easy to modulate waveforms. The U2761A connects to the computer through Hi-Speed USB 2.0 connectivity.

*This is a Web introductory price for one calibration of the KEYSIGHT U2761A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
