General Information
L-Series coaxial multiport switches overview
Keysight L-series coaxial multiport switches consists of two main group of
products. L7104A/B/C and L7106A/B/C are terminated switches with SP4T and
SP6T configuration respectively while L7204A/B/C and L7206A/B/C are
unterminated SP4Ts and SP6Ts. Both terminated and unterminated L-series
coaxial multiport switches provide the life and repeatability for automated test
and measurement, signal monitoring and routing applications with reasonable
cost.
Figure 1 L-series coaxial multiport switches - L7106C and L7104C
Keysight L-Series Operating and Service Manual 1
Features
SP4T and SP6T configuration with magnetic latching
– Warranted 0.03 dB insertion loss repeatability for 2 million cycles
– Excellent isolation, typically > 85 dB at 26.5 GHz
– Opto-electronic indicators and interrupts
– TTL/5V CMOS compatible (optional)
– Terminated and unterminated ports
Innovative design and careful process control creates switches that meet the
requirements for highly repeatable switching elements in test instruments and
switching interfaces. The exceptional 0.03 dB insertion loss repeatability is
warranted for 2 million cycles at 25°C. This reduces sources of random errors in
the measurement path and improves measurement uncertainties. Switch life is a
critical consideration in production test systems, satellite and antenna monitoring
systems, and test instrumentation. The longevity of these switches increases
system uptime, and lowers the cost of ownership by reducing calibration cycles
and switch maintenance.
Table 1 shows the 12 models of L-series coaxial multiport switches available.

Driving the switch
Each RF path can be closed by applying ground (TTL “High” for Option T24) to the
corresponding “drive” pin. In general, all other RF paths are simultaneously
opened by internal logic. See Figure 2 for drive connection diagrams.
Figure 2 Drive connection diagram for Option 161 and Option 100
Keysight L-Series Operating and Service Manual 3
The default operation of the switches is break-before-make. Make-before-break
NOTE
CAUTION
NOTE
switching can be accomplished by simulataneously selecting the “drive” pins for
old RF path and new RF path. This will simultaneously close the old RF path and
new RF path. Once the new RF path is closed (15 ms), de-select the old RF path
“drive” pin while leaving the new RF path “drive” pin selected. The switch circuitry
will automatically open the old RF path while leaving the new RF path engaged.
Standard drive
– Connect pin 1 to supply voltage (+20 Vdc to +32 Vdc) and pin 15 to ground.
Pin 15 must always be connected to ground to enable the electronic
position-indicating circuitry and drive logic circuitry.
If pin 15 is not connected to power supply ground, catastrophic failure will
occur.
– Select (close) desired RF path by applying ground to the corresponding “drive”
pin; for example ground pin 3 to close RF path 1.
After the RF path is switched and latched, the drive current is interupted by the
electronic position-sensing circuitry.Pulsed control is not necessary, but if
implemented, the pulse width must be 15 ms minimum to ensure the switch is
fully latched.
– To select another RF path, ensure that all unwanted RF path “drive” pins are
disconnected from ground (to prevent multiple RF path engagement). Ground
the “drive” pin which corresponds to the desired RF path.
– To open all RF paths, ensure that all RF path “drive” pins are disconnected
from ground. Then, connect pin 16 to ground. This feature is not available in
option 100.

TTL drive (Option T24)
NOTE
CAUTION
NOTE
– Connect pin 1 to supply voltage (+20 Vdc to +32 Vdc) and pin 15 to ground.
Pin 15 must always be connected to ground to enable the electronic
position-indicating circuitry and drive logic circuitry.
In addition to the quiescent current supplying the electronic position-sensing
circuitry, the drive current flows out of pin 15 (during switching) on TTL drive
switches (option T24).
If pin 15 is not connected to power supply ground, catastrophic failure will
occur.
– Select (close) desired RF path by applying TTL “High” to the corresponding
“drive” pin; for example apply TTL “High” to pin 3 to close RF path 1.
After the RF path is switched and latched, the drive current is interupted by the
electronic position-sensing circuitry.Pulsed control is not necessary, but if
implemented, the pulse width must be 15 ms minimum to ensure the switch is
fully latched.
– To select another RF path, ensure that all unwanted RF path “drive” pins are at
TTL “Low” (to prevent multiple RF path engagement). Apply TTL “High” to the
“drive” pin which corresponds to the desired RF path.
– To open all RF paths, ensure that all RF path “drive” pins are at TTL “Low”.
Then, apply TTL “High” to pin. This feature is not available in option 100.
Keysight L-Series Operating and Service Manual 5
Electronic position indicators
The electronic position indicators consist of optically isolated, solid state relays
which are driven by photo-electric sensors coupled to the mechanical position of
the RF path’s moving elements (See Figure 3). The circuitry consists of a common
which can be connected to an output corresponding to each RF path. If multiple
RF paths engaged, the position indicator corresponding to each closed RF path
will be connected to common. The solid state relays are configured for AC and/or
DC operation. See Table 3 for indicator specifications. The electronic position
indicators require that the supply (20 to 32 VDC) be connected to pin 1 and
ground connected to pin 15.

Installation
Initial inspection
1 Inspect the shipping container for damage. If the shipping container or
cushioning material is damaged, it should be kept until the contents of the
shipment have been checked for completeness and the instrument has been
checked both mechanically and electrically.
– Check for mechanical damage such as scratches or dents.
– Procedures for checking electrical performance are given under Operator’s
check or Performance Tests.
2 If the contents are incomplete, if there is mechanical damage or defect, or if
the instrument does not pass the electrical performance test, contact the
nearest Keysight Technologies Sales and Service office. Refer to the Sales and

Operating Instruction
CAUTION
Operator’s check
The operator’s check is supplied to allow the operator to make a quick check on
the coaxial multiport switches prior to use or if a failure is suspected.
ESD exceeding the level specified in Table 9 or RF power applied is greater
than the maximum specified as in Table 2 may cause permanent damage to
the device.
Description
The coaxial multiport switch is connected to a network analyzer configured for the
s-parameter measurement. The network analyzer may be set to sweep over the
whole or selected frequency range of the switch to be verified. The s-parameters
measurement is the best way to determine if the switch is working properly.

Quick-check procedure
1 Connect common port of switch to Port 1 of the network analyzer and one of
the outer RF ports to Port 2 of network analyzer as illustrated in Figure 8.
2 For standard drive, apply ground to the corresponding “drive” pin to close the
selected path. Refer to “Standard drive” on page 4.
3 For TTL drive (option T24), apply “High” to the corresponding “drive” pin to
close the selected path. Refer to “TTL drive (Option T24)” on page 5.
4 Perform s-parameters measurement and verify against specifications in
Table 4, Table 5 or Table 6.
5 Repeat from step 1 until all paths are measured and verified.
