In Figure 5, an active device, such as an amplifier, is inserted into
a signal path presenting a unique problem. A single transfer switch
has the undesirable characteristic of shunting the output of the
amplifier to its input when the signal is bypassing the amplifier.
The advantage of using two transfer switches is that an additional
signal path is available, however two SPDT switches can also be
used. This additional path can utilize the same amplifier when the
original path is bypassed.

Driving the switch
There are two positions for the Agilent 87222C/D/E transfer
switch. See Table A on page 123. Position A has RF Port 1
connected to RF Port 2 and RF Port 3 connected to RF Port 4.
Position B has RF Port 2 connected to RF Port 3 and RF Port 1
connected to RF Port 4. The switch can be driven with a standard
grounding drive control with or without a separate ground. Single
line or dual line TTL control are also available. The switch operates
in a break-before-make mode.
Caution 11713A switch driver users: Do not drive the 87222C/D/E
using the S9 or S0 outputs from either the banana-plug outputs or
the Viking connectors located on the rear panel of the 11713A.

(I) Standard drive:
See Figure 6 on page 123 for drive connection diagrams.
• Connect Pin 1 to supply (+20 VDC to +32 VDC)
• Connect Pin 9 to ground (see note 1)
• Select position “A” by applying ground to Pin 3 (see note 3)
• Select position “B” by applying ground to pin 5 (see note 3)
(II) Single line TTL drive:
See Figure 6 on page 123 for drive connection diagrams.
See Figure 7 on page 123 for TTL voltage states.
• Connect Pin 1 to supply (+20 VDC to +32 VDC)
• Connect Pin 9 to ground (see notes 2, 4)
• Connect Pin 8 to TTL “High”
• Select position “A” by applying TTL “High” to pin 7 (see note 3)
• Select position “B” by applying TTL “Low” to pin 7 (see note 3)
(III) Dual line TTL drive:
See Figure 6 on page 123 for drive connection diagrams.
See Figure 7 on page 123 for TTL voltage states.
• Connect Pin 1 to supply (+20 VDC to +32 VDC)
• Connect Pin 9 to ground (see notes 2, 4)
• Select position “A” by applying TTL “High” to pin 7 and TTL
• Select Position “B” by applying TTL “Low” to pin 7 and TTL
Notes:
1. Pin 9 does not need to be grounded for the switch to operate in standard drive
2. For TTL drive, pin 9 must be grounded.
3. After the RF path is switched and latched, the drive current is interrupted by

mode. If pin 9 is not grounded, the position indicators will only function while
the appropriate drive has ground applied. Therefore, if a pulse drive is used and
continuous indicator operation is required, pin 9 must be grounded.

implemented, the pulse width must be 15 ms minimum to ensure that the
switch is fully latched.
circuitry, the drive current flows out of pin 9 (during switching) when using TTL
drive.
