Safety Summary
The following general safety precautions must be observed during all phases of operation,
service, and repair of this instrument. Failure to comply with these precautions or with speci c
WARNINGS given elsewhere in this manual violates safety standards of design, manufacture,
and intended use of the instrument.
The Agilent Technologies assumes no liability for the customer's failure to comply with these
requirements.
DO NOT Operate In An Explosive Atmosphere
Do not operate the instrument in the presence of
ammable gasses or fumes. Operation of any
electrical instrument in such an environment constitutes a safety hazard.

Repackaging the Test Fixture for Shipment
If shipment to an Agilent Technologies service center is required, each test xture should be
repackaged using the original factory packaging materials.
If this material is not available, comparable packaging materials may be used. Wrap the 16194A
in heavy paper and pack in anti-static plastic packing material. Use sucient shock absorbing
material on all sides of the 16194A to provide a thick, rm cushion and to prevent movement.
Seal the shipping container securely and mark it FRAGILE.

Setting the open condition
Operating Flow
The following shows typical operating procedure. Before performing a measurement, it is
necessary to compensate for the residual error of the xture. The error compensation functions
are dierent for each instrument. For procedure on how to perform each error compensation,
see the Operation Manual supplied with your analyzer.
1. Perform calibration at the measurement terminal of your analyzer, and connect the 16194A.
2. Perform electrical length compensation(Fixture Select/Port Extension).
3. Perform SHORT compensation.
For both surface mount device and leaded device measurements, use the shorting device.
4. Perform LOAD compensation, if necessary.
For both surface mount device and leaded device measurements, use the 50
chip resistor
as a LOAD device. The reference value for LOAD compensation is R=50
/ L=0 H.
5. Perform OPEN compensation.
6. Measure the device under test.
Note In case of using the 4291B with option 013/014 High Temperature Test Head,
the recommended error compensation is as follows.
When using option 013 : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : OPEN/SHORT/LOAD
When using option 014 below 500MHz : : : : : : : : : : OPEN/SHORT, Fixture Select

Operation 3-1
Warning The 16194A has the capability for 055 C to +200 C temperature
measurement in environmental testing. Use gloves to prevent burns when
handling heated parts.
Connecting the Test Fixture for Use
1. Calibrate your analyzer at the APC-7
connector plane before connecting the test xture.

3-2 Operation
Placing Shorting Device, Load Device, or Device Under Test
1. Adjust the position of the ground plate and tighten its knob.
2. Adjust the position of the device holder so that it presses against the device. When
measuring a leaded device, adjust the distance between the two pins to the device size.
Then tighten the knob of the device holder.
3. Move the arm outward.
4. Place the device on the electrodes and press it with the device holder (Figure 3-2 (b) - (d) ).
When placing a leaded device, put its leads on the notch of the 16194A's electrodes.
You can adjust the pressure of the arm by turning the pressure adjustment using the wrench.
Figure 3-2. Placing the Device
Operation 3-3
Setting the Open Condition
1. If there is any device on the electrodes, remove it.
2. When measuring a surface mount device, move the arm outward and latch it. Then make
the distance between the electrodes same as the device size by adjusting the ground
plate(Figure 3-3 (a) ).
3. When measuring a leaded device, make the distance between the electrodes and the
distance between the device holder's pins same as the device size. Then press the electrodes
with the device holder's pins, not latching the arm(Figure 3-3 (b) ).
