Tektronix 3723

The 3723 offers two independent banks of high speed 1×30 two-pole multiplexers that are ideal for high speed scanning applications. The two banks can automatically be connected to the Series 3700A mainframe backplane and optional DMM through the analog backplane connection relays. This connection allows the mainframe to reconfigure the 3723 as a single 1×60 two-pole multiplexer or as a single 1×120 single-pole multiplexer. It also enables card-to-card expansion for even larger configurations.

Key Features

• 60 two-pole or 30 four-pole channels for high speed scanning
• 120 channel single-pole mode for one-wire (common side) measurements
• Analog backplane connection relays provide easy bank and card interconnections
• 200 V, 1 A switched or 1.25 A carry signal capacity; 15 W
• Relay actuation time <0.5 ms
• 20 MHz bandwidth
• Ideal for multi-channel I-V testing with Series 2600B SourceMeter® SMU instruments
• Long life dry reed relays (>10⁹ operations)

By using high speed reed relays with actuation times of less than 0.5ms, this card can meet demanding throughput applications. Another feature of the 3723 is its single-ended, one-pole mode, which supports up to 120 channels of single-wire measurements.

The 3723 uses two 78-pin D-sub connectors for signal connections. For screw terminal connections, use the 3723-ST for two- and four-pole configurations.
