1-4 Getting Started Model 2701 User’s Manual
Model 7705 — This control module provides 40 independent 1-pole switching (SPST)
channels that are isolated from the internal DMM.
Model 7706 — This all-in-one module provides 20/10 channels of 2/4-pole input,
16 digital outputs, two analog outputs, and one 32-bit counter with gating and totalizer.
Model 7707 — This module provides 10 channels of 2-pole input or 5 channels of 4-pole
input. Also provides four independent 8-byte digital I/O channels.
Model 7708 — This differential multiplexer provides 40 channels of 2-pole input or
20 channels of 4-pole input. The internal cold junction allows direct-connection of
thermocouples for temperature measurements.
Model 7709 — This module is configured as a 6
×
8 matrix (six rows, eight columns).
The matrix consists of 48 crosspoint channels and two backplane isolation channels. For
system channel operation, row 1 (8 channels) is connected to DMM Input. For 4-wire
measurements, rows 1 and 2 (4 system channels) are connected to the DMM.
Model 7710 — This differential multiplexer provides 20 channels of 2-pole input or
10 channels of 4-pole input. The internal cold junction allows direct-connection of
thermocouples for temperature measurements. This module provides high-speed
switching and uses long-life relays.
Model 7711 — The Model 7711 is a 50
Ω
, 2GHz, single-pole dual 1
×
4 RF Multiplexer
module (eight channels, no measurement capability). This 1
×
4 multiplexer is a cascad-
ing tree design — one of the channels of each is always connected to a common out. It can
be used to connect one instrument to multiple devices or multiple instruments to a single
device.
Model 7712 — The Model 7712 is a 50
Ω
, 3.5GHz, single-pole dual 1
×
4 RF Multiplexer
module (eight channels, no measurement capability). This 1
×
4 multiplexer is a cascad-
ing tree design — one of the channels of each is always connected to a common out. It can
be used to connect one instrument to multiple devices or multiple instruments to a single
device.
Cables and connector kits for switching modules
Model 7788 DB-50 connector kit — Contains two male DB-50 solder cup connectors
with strain relief connector shells. These connectors mate to the female connectors of the
Models 7703 and 7705 switching modules.
Model 7789 50/25-pin solder cup connector kit — Contains one male DB-50 and one
male DB-25 solder cup connectors. These connectors mate to the female connectors on the
Models 7701 and 7709 switching modules.
Model 7790 ribbon cable adapter kit — Contains one female DB-50, one male DB-50,
and one male DB-25 IDC ribbon cable connectors. These connectors are used with the
Models 7701, 7707, and 7709 switching modules.
Model 7051-X — BNC cable (male to male). 7051-2 is 2 ft long, 7051-5 is 5 ft long, and
7051-10 is 10 ft long. These cable are used with the Model 7711 switching module.
