Agilent Switch Description
N1810UL Unterminated latching 3-port (SPDT)
N1810TL Terminated latching 3-port (SPDT)
N1811TL Terminated latching 4-port (transfer)
N1812UL Unterminated latching 5-port
Option Name Option Number Description and Comments
Frequency Range various All options supported
Coil Voltage 105 +5VDC

Highest coil current requirement of all coil voltage
options. May limit system speed because current
capacity limitations. This option draws 600 mA

(except N1810UL 300 mA). Therefore, a maximum
of 3 (6) devices may be switched simultaneously.
115 +15VDC
124 +24VDC (required if using internal power)
DC Connector Type 201 D-Sub 9 pin female
202 Solder lugs

Can use ribbon cables with the Y1150A, or discrete
wires with the Y1155A.
RF Performance various All options supported
Drive Options 401 TTL/CMOS compatible

All switches on the same distribution board must use
the same drive mode.
402 Position indicators (required to use verification
feature)
403 Current interrupts

For pulsed operation, current interrupts are not
required. May provide system switching speed
improvements.
