In the RF region, the wavelengths are short and are not negligible compared to the physical
transmission line length of the test xture. This causes a phase shift error. The phase shift
error is compensated by the electrical length parameter for the test xture. Because the
electrical length values for the Hewlett Packard test xtures are stored in the HP 4286A, you
can set the electrical length parameter by selecting the xture model number.

Setting up Handler Interface Board
This section describes the steps necessary to use the handler interface board.
There are 3 major steps as follows:
Mounting Pull-up Resistor
Mount a pull-up resistor to the handler. Where to mount a resistor and what resistance the
resistor needs to have depends on the signal I/O format.
Note
A pull-up resistor must be mounted to the handler for comparator signals.
Setting up Handler Interface
Set up the handler interface signal pattern that suits the HP 4286A operation mode. Set it up
on the HP 4286A.
The following step is required when the power supplies for I/O or COMMON setting should be
modied.
Changing Signal I/O Format
Change the switch setting on the handler interface board to change its signal I/O format.
This is necessary when you need the I/O format that requires the switch settings dierent
from the default settings.
Checking Default Settings
The handler interface board has been set as follows before shipment.
Signals Settings
Comparator Signal This signal is opto-isolated and is output through open-collector
COM1 is used as COMMON that is isolated from HP 4286A's
chassis ground. Pull-up resistors are mounted to the handler
.
Output voltage is supplied from an external power source (5 to
24V) on the handler.
Control Output Signal This signal is opto-isolated and is output through open-collector
COM2 is used as COMMON that is isolated from HP 4286A's
chassis ground. Pull-up resistors are mounted to the handler.
Output voltage is supplied from an external power source (5 to
15V) on the handler.
DC isolated Input Signal This signal is opto-isolated from the internal circuits of
HP 4286A. Driving voltage is supplied from an external power
source (5 to 7V) through EXT.DCV2. This signal turns \TRUE" if
input signal is connected to the COMMON of the external power
source.
Internal power source (5V) Not used.

HP 4286A Measurement Time
Total measurement time of the LCR meter is calculated as follows:

/INDEX(until the end of list sweep)
Comparator

Measured value display 3ms+6ms/point
Handler signal output 0.1ms
/EOM
Data transfer through HP-IB 20ms/
(contact check +2 measurement points)

By incrementing the averaging factor by 1, total measurement time becomes 5ms
longer.For example, analog measurement time is 30ms ( = 15ms + 5ms23 ) when you
select 4 for the averaging factor.
You can turn the measured value display ON/OFF on the front panel. When you set this
function to OFF, the duration of time between EOM(End of Measurement) and next trigger
becomes shorter.
The data transfer time through HP-IB shown above includes the time required to input a
contact check comparator signal and 2-point measurement results at the same time using the
HP 9000 Series 360.
Example
The following shows the approximate duration of time required to make a 2-point measurement
by list sweep.We assume that the measured value display, comparator, and handler signal
output are respectively OFF, ON, and ON.
Calculating the time for each operation from the above

Electrical Specication of Handler Interface
The handler interface sends results of comparison from the HP 4286A to the handler interface
and allows timing control signals for measurements and handler operation to be exchanged
between the HP 4286A and handler interface.
Using these signals you can congure a highly ecient chip handling system.
This section provides the pin assignment of the handler interface connector, description of each
signal, and timing diagram of these signals.

Electrical Characteristics of Signals
This section provides description of electrical characteristics of each signal and conguration of
I/O circuits.
Electrical characteristics of each signal do not change regardless of the function (comparator
function and list sweep comparator function) used.
DC Isolated Output Signals
Each of the DC isolated signals (pins 1 to 11, 19 to 24, 29 to 31) is output through an
open-collector and photocoupler.
You can use switches on the handler interface board to select the desired power source. The
internal source (5V) or an external power source (5 to 24V for comparator output signals or 5 to
15V for control output signals) can be selected. Note that you usually use an external power
source to supply voltage to control output signals.
You can connect the internal pull-up resistor of 4.7k to control signals by simply changing
switch settings. Note that you must mount a pull-up resistor to the handler side of the board
for comparator output signals.

Restoring Settings After Power Interruption
Instantaneous power interruption resets the HP 4286A to default settings. The HP 4286A must,
therefore, be set to your own settings again after power interruption. To do this, you can use
the backup SRAM disk memory or built-in exible disk drive to automatically restore your
settings.
When you wish to use the exible disk drive, rst save your settings in the le named
on a exible disk. Then, insert this disk in the disk drive and keep it inserted while the
HP 4286A is running. When you wish to use the SRAM disk memory, save the
the disk memory. In either case, the HP 4286A will read the contents of this le to recall its
settings and calibration data if the power is interrupted. AutoRecall provides a fast way to
recover your HP 4286A settings after power interruption.
Note
When you have the
disk memory, the contents of the le in the exible disk will be read into the
HP 4286A.
All data in the disk memory will be lost in 3 days after power interruption.
Backup batteries can be automatically recharged when the HP 4286A is ON.

Further Discussion
Point Averaging averages each data point by a user-specied averaging factor
. The HP 4286A
repeats measuring the same point until the averaging factor is reached. It then divides the
vector summation of measurement values by the averaging factor and starts measuring the
next point.
For some other impedance analyzers, 2 types of avaraging methods are available, which is
sweep averaging method and point avaraging method. When you compare results with those
obtained by other impedance meter or analyzer, be sure that the both measurement are
based on point averaging method.
