Description
N2260A 40-Channel MUX
Module
1 Latching In 3488 mode, a 40-channel 2-
wire multiplexer, switches both
HI and LO inputs (200 V, 1 A)
with DPST relays.
N2266A 40-Channel MUX
Module
1 Reed non-
latching
In 3488 mode, a 40-channel 2-
wire multiplexer.
N2268A 50Ω 3.5 GHz Dual
4-to-1 MUX
Module
1 Latching Consists of two independent 1-
to-4 MUX switches which can
switch up to 30VDC or peak AC
at frequencies from DC to
3.5 GHz.
N2270A 10-Channel High
Voltage MUX
Module
2Non-
latching
10-channel 2-wire High Voltage
MUX module with maximum
switching voltage 1000V peak
and maximum switching power
10W.
44470A/D 10/20-Channel
MUX Module
1 Latching The 10/20 DPST (Double-pole
Single-throw) relays switch both
HI and LO inputs up to 250V,
2A with low differential offsets
for accurate measurements.
44472A Dual 4-Channel
VHF Switch
Module
1 Latching The two independent groups of
bidirectional 1x4 switches with
50Ω characteristic impedance
can be used for signals from
DC to 300 MHz.
44478A/B 50Ω/75Ω 1.3 GHz
Multiplexer
1 Latching The two independent groups of
bidirectional 1x4 switches with
50Ω/75Ω characteristic
impedance can be used for
signals from DC to 1.3 GHz.
