2 Keysight 16495 Installation Guide, Edition 6
Installation Guide
Keysight 16495 connector plate is the interface to connect your prober or test fixture
to the instruments (Keysight B1500/E5260/E5270/4142/4155/4156 semiconductor
parameter analyzers, Keysight B2200/E5250 switching matrix, and so on).
This manual provides the information to install the connector plate, and consists of
the following sections:
•“Connector Plates” introduces the 16495C/D/E/F/G/H/J/K connector plates.
•“Required Parts” lists the parts needed to install the connector plate.
•“Installing Connector Plate” describes how to install the connector plates on
your shielding box for prober or fixture.
•“Installing Interlock Circuit” describes how to install the interlock circuit on
your shielding box.
•“Connecting DUT Cables” describes how to connect the cables between the
connector plate and the DUT interface such as manipulators and probe card.
WARNING You should install the connector plate on your shielding box for prober or test
fixture. And you should install an interlock circuit on the door of shielding box.
The reasons are:
• To prevent the operator from receiving an electric shock by the voltage or
current applied from instrument during measurement.
• To minimize the effects of environmental noise and ambient light.
If the instrument has the interlock capability, you must make the interlock
circuit on your shielding box, and connect the instrument to the interlock
connector on the connector plate. See “Installing Interlock Circuit” on page 11
and “To Connect Interlock Cable” on page 15. When you open the shielding
box door, the voltages applied to the DUT are reduced automatically to a
non-dangerous level.
If you use an instrument that does not have the interlock capability, dangerous
voltages can still be applied to the DUT even when you open the shielding box
door.

used with the Keysight E5288A Atto Sense/Switch Unit (ASU) or the Keysight
N1301A-200 Guard Switch Unit (GSWU) that will be installed in the shielding box.
The cable hole is to pass the cables from the ASU or GSWU to the instrument such
as the Keysight B1500A, E5270B, and so on. And the cables will be fixed to the
shielding box by using the cover with rubber that will close the opening of the cable
hole.

Installing Connector Plate
Installing Connector Plate
This section explains how to install the connector plates on your shielding box for
prober or test fixture.
Before installing the connector plate, do the following.
1. Prepare the parts required for installing the connector plate. See Table 1.
2. Ground the shielding box if it is not grounded.
3. On the shielding box, create openings and screw holes that match the size of
connector plate. The dimensions for the openings and screw holes are as
follows.
• Screw holes: 3 mm in diameter
• Openings:
• Half size connector plate: 95 mm (W) 200 mm (H)
• Full size connector plate: 210 mm (W) 200 mm (H)
For the position of the screw holes, see “Connector Plates” on page 3.
4. If any instrument is connected to the connector plate, turn it off.
5. Disconnect all cables from the connector plate.
Install the connector plate as shown below.
1. For the 16495C/D/F/G/H/J-002, remove the shield cover from wiring side of
connector plate by removing screws on the connector plate.
2. Install the interlock circuit to the shielding box. See “Installing Interlock
Circuit” on page 11.
3. Make connections between the connector plate and the DUT interface, such as
manipulators and probe card. See “Connecting DUT Cables” on page 16.
4. Fix the connector plate on the shielding box by using the screws, nuts, and
washers. See Figure 3. This will ground the connector plate.
5. For the 16495C/D/F/G/H/J-002, re-attach the shield cover to the connector plate.
This will ground the cover and avoid the chance to touch the soldered joints.
6. For the 16495K, continue the procedure shown in “To Install 16495K” on page
10.

Pass the ASU control cable and measurement cables, or pass the GSWU control
cable through the cable hole as shown below. See Figure 4 or Figure 5.
1. Remove the cover with rubber by removing screws on the 16495K plate.
2. Pass the ASU cables or the GSWU cable through the cable hole, and adjust the
cable length inside the shielding box. The cables must be connected between the
unit (ASU or GSW) and the instrument such as the Keysight B1500A, E5270B,
and so on.
3. Re-attach the cover with rubber to the 16495K plate. The cables will be
sandwiched between the cover and the plate. And the cable hole will be closed.

Installing Interlock Circuit
Installing Interlock Circuit
Interlock circuit is to prevent electric shock when touching measurement terminals.
Before installing the connector plate, you must install an interlock circuit to prevent
dangerous voltages when door of shielding box is open.
This circuit can be made with an instrument that has the interlock capability, such as
the Keysight B1500/E5260/E5270/4155/4156.
The following figure shows the pin assignments of the Intlk connector on the
connector plate and the interlock circuit you need to make on your shielding box.
Recommended parts for making interlock circuit are shown in Table 1.
Figure 6 Interlock Connector
NOTE Intlk Connector
Intlk connector on the connector plate is compatible with the Intlk connector of the
Keysight B1500/E5260/E5270/4155/4156.
If you use an instrument that has a BNC type interlock connector (such as the 4142),
use the Keysight 16435A interlock cable adapter and Keysight 16493J interlock
cable.
To connect the interlock connector of instrument and connector plate, see “To
Connect Interlock Cable” on page 15.

Installing Interlock Circuit
To Install Interlock Circuit
Install the interlock circuit as follows.
1. Fix two mechanical switches on your shielding box, so that the switches close
when the door of the shielding box is closed, and open when the door is opened.
For the dimensions of the switches, see Figure 7 and Figure 8.
2. Use wire and connect the two switches in series between pin number 1 and 2 (or
3) of the Intlk connector. See Figure 6.
For example, if the Keysight B1500/E5260/E5270/4155/4156 is connected to the
Intlk connector, it cannot force dangerous voltage, more than ±40 or 42 V depending
on the instrument, when the door is open. When the door is closed, it can force the
dangerous voltage. For details of interlock capability, see the manual of the
instrument you use.
