Keysight I/O libraries Keysight’s IO Library Suite helps you quickly establish an error–free connection between your

PC and instruments, regardless of the vendor. It provides robust instrument control and works

with the software development environment you choose.

General Specifications

Power requirements 350 W typical, 400 W maximum

Operating temperature range 0 to 50 ˚C

Storage temperature range –40 to 70 ˚C; during storage below –20 ˚C, instrument states and waveform data may be lost.

Altitude 0 to 3000 m (10,000 ft)

Humidity Type tested, 95% relative humidity at 40 °C decreasing linearly to 50% relative humidity at 50 °C.

Environmental testing Samples of this product have been tested in accordance with the Keysight Environmental Test

manual and verified to be robust against the environmental stresses of storage, transportation,

and end–use. Those stresses include but are not limited to temperature, humidity, shock,

vibration, altitude, and power line conditions. Test methods are aligned with IEC 60068–2 and

levels are similar to MIL–PRF–28800F Class 3. Phase noise specifications are not warranted in a

vibrating environment.

ISO compliant This family of signal generators is manufactured in an ISO–9001 registered facility in

concurrence with Keysight’s commitment to quality.

EMC Conforms to the immunity and emission requirements of IEC/EN 61326–1 including the

conducted and radiated emission requirements of CISPR Pub 11/2009 Group 1, Class A.

Storage Memory is shared by instrument states and waveform files.

The solid–state drive initially holds at least 512 GB of free space.

Security Display blanking

Memory clearing functions (See Application Note, Security Features of Keysight Technologies Signal

Generators, part number E4400–90621).

Removable Solid State Drive (SSD) with all user data.

Self–test Internal diagnostic routine tests most modules in a preset condition. If node voltages are within

acceptable limits, then the module passes the test.

Weight 17.2 kg (38.0 lb) net

24.0 kg (52.8 lb) shipping

Dimensions 103 mm H x 426 mm W x 559 mm D (4.05” H x 16.8” W x 22.0” D)

Height and depth dimensions include bottom and rear panel feet.
