OSP-B142 RF SSR Power Module
Figure 3-132: R&S
OSP-B142, with up to 3 DP3T relays in horizontal lines (flat relay design)
Left
= Version .03 with 3 DP3T relays and no terminations
Center top
= Version .11 with 1 DP3T relay and 2 external 50
Ω
terminations, the function is like a termi-
nated SPDT
Center below = Version .12 with 2 DP3T relays, each with 2 external 50
Ω
terminations, the function is like 2
terminated SPDTs
Right
= Version .13 with 3 DP3T relays, each with 2 external 50
Ω
terminations, the function is like 3
terminated SPDTs
The port labeled P1 is equivalent with the position NO and the port labeled P2 is equiv-
alent with the position NC in the "WebGUI" (
) and in the description below.
The one-slot
OSP-B142 (order no. 1505.4792.03/.11/.12/.13) consists of
1, 2 or 3 solid-state power relays (see below). The relays with SMA (female) connec-
tors can handle up to 10
W (40
dBm) of RF power in the frequency range 9
kHz to
8
GHz.

connectors.
The switch module is available in 4 versions:
●
Order no. 1505.4792
.03
: 3 DP3T relays without external termination
●
Order no. 1505.4792
.11
: 1 terminated DP3T relay in position K1, equivalent with 1
terminated SPDT relay
●
Order no. 1505.4792
.12
: 2 terminated DP3T relays in position K1 and K2, equiva-
lent with 2 terminated SPDT relays
●
Order no. 1505.4792
.13
: 3 terminated DP3T relays in position K1 to K3, equivalent
with 3 terminated SPDT relays
The relays are factory-configured starting from position K1 onwards, hence, there is no
configuration with K1 and K3, only. Openings without a relay are covered from the
inside by a strip of sheet metal.
