HP 44472A

The 44472A VHF Switch provides broadband switching for high-frequency and pulse signals. The two independent groups of bidirectional 1 x 4 switches can be used for signals from dc to 300MHz. All channels have 50 ohm characteristic impedance and are break-before-make within a group of four channels. Each group is isolated from the other and from ground to prevent ground loops. Excellent isolation makes this module ideal for high-frequency signal analyzer measurements requireing a large dynamic range. This unit is Option 012 plug-in module for the 3488A Switch/Control Unit.
