1-4 Getting Started Model 2750 Multimeter/Switch System User’s Manual
Model 7703 — This differential multiplexer provides 32 channels of 2-pole input, or 16
channels of 4-pole input.
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 digi-
tal outputs, two analog outputs, 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 32 digital inputs/outputs.
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 thermo-
couples 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 is connected to DMM Input. For 4-wire measurements,
row 2 is connected to DMM Sense.
Connector and adapter 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.
Cables and adapters (GPIB and trigger link)
Models 7007-1 and 7007-2 shielded GPIB cables — Connect Model 2750 to the GPIB
bus using shielded cables and connectors to reduce electromagnetic interference (EMI).
Model 7007-1 is one meter long; Model 7007-2 is two meters long.
Models 8501-1 and 8501-2 trigger link cables — Connect Model 2750 to other instru-
ments with Trigger Link connectors (e.g., Model 7002 Switch System). Model 8501-1 is
one meter long; Model 8501-2 is two meters long.
Model 8502 trigger link adapter — Lets you connect any of the six trigger link lines of
Model 2750 to instruments that use the standard BNC trigger connectors.
Model 8503 DIN to BNC trigger cable — Lets you connect trigger link lines one (Volt-
meter Complete) and two (External Trigger) of Model 2750 to instruments that use BNC
trigger connectors. Model 8503 is one meter long.
