Product Description:
Use the Agilent 34908A to achieve maximum density in common low applications, such as cell testing, component characterization, and benchtop testing.
Each module switches 40 single-wire inputs. Supports all 2-wire internal measurements except current. The low level connection of the module is isolated from the ground, and the voltage can be floating up to 300 V.
Module Specifications Agilent 34970A Precision specifications are included in the chart
Switch offset and reference junction error as shown in. These errors are listed separately and used to determine the systematic errors of the external measurement equipment. These errors are listed separately and used to determine the systematic errors of the external measurement equipment.
Up to three modules of any combination can be inserted into a single host. The internal DMM connection of the 34970A can only be accessed through the 34901A, 34902A, and 34908A low-frequency multiplexers.
The screw terminals on the module accept wire sizes from 16 gauge to 22 gauge. For high channel count applications, line 20 is recommended. The 34905A and 34906A RF multiplexers use SMB connectors. Each RF module is supplied with a standard (10) BNC to SMB adapter cable for easy BNC connection.
