Equipment information

Keithley 7064 Interface
Manufacturer
Keithley
Model: 7064
Date: 1984
Category: Measurement instruments
Group: Interface
Description: Low Voltage Scanner Card
Information:
                                    The Model 7064 is a 20 channel low-voltage scanner card. The
card is designed to introduce a minimum of voltage offset
error (less than 1/xV differential thermal offset from input
to output with copper leads) for sensitive tests such as
low-level transducer and thermocouple output switching.
Channel switching allows one signal to be switched to as
many as 20 channels or 20 channels to one channel. In the
latter configuration the channels are switched one at a time.

The Model 7064 works in conjunction with an appropriate
scanner mainframe such as the Keithley Model 705 or Model
706. The card is configured as desired then plugged into the
mainframe. The mainframe controls channel switching using
either the front panel controls or commands over the
IEEE-488 bus. With multiple Model 7064 cards and several
Model 706 mainframes daisy chained together, up to 1000
channels can be switched.
High channel isolation, 10¹²Ω, minimizes cross channel
interference and noise. Expected relay life, greater than
1,000,000 closures, is obtained when signals less than 10V
or 10mA are switched (non-inductive load only). However,
peak signals up to 40V or 100mA can be switched. Quick
disconnect screw terminals facilitate input and output
connections to the scanner card.
