Instruments Covered by Manual
Agilent T
echnologies uses atwo-part, ten character serial number which is stamped on the
serial number plate (see Figure 1-1) attached to the rear panel. The rst ve letters are the
serial prex and the last ve digits are the sux. The prex is the same for all identical
instruments; it changes only when a change is made to the hardware of the E4915A/E4916A.
The sux, however
, is assigned sequentially and is unique to each instrument. The contents of
this manual apply to instruments with the serial number prexes listed under Serial Numbers
on the title page
.

Introduction
This section describes the A
djustments and P
erformance T
ests required for the E4915A/E4916A
Crystal Impedance / LCR Meter to operate within its specications
.These adjustments
and performance tests should be performed along with periodic maintenance to keep the
E4915A/E4916A in optimum operating condition. The recommended calibration period is 12
months
.

Safety Considerations
This manual contains NOTEs
,CA
UTIONs
,and W
ARNINGs which must be followed to ensure
the safety of the operator and to keep the instrument in asafe and serviceable condition. The
adjustments and performance tests must be performed by qualied service personnel.
W
arning
Any interruption of the protective ground conductor (inside or outside
the instrument) or disconnection of the protective ground terminal can
make the instrument dangerous
.Intentional interruption of the protective
ground system for any reason is prohibited.
The removal or opening of covers
,or removal of parts other than those which are accessible by
hand will expose circuits containing dangerous voltage levels
.
Remember that the capacitors in the E4915A/E4916A can remain charged for several minutes
even though the E4915A/E4916A is o and unplugged.

est
Program
T
o use the E4915A/E4916A adjustment/performance test program, it is rst necessary to install
an GPIB Card. This section describes how to install it.
Installing an GPIB Card (82340 or 82341)
Install an GPIB Card in your computer (see the GPIB Card manual). The select code of the
GPIB Card should be set to \7". The GPIB Card should be the 82340 or the 82341A. Other
GPIB Cards can not be used in the Windors NT environment.
Installing HP VEE for Windows NT
Install the HP VEE for Windows NT in your computer (see the HP VEE for Windows NT
manual).
After installing HP VEE for Windows NT
,run the
I/O Cong
utility in the
HP VEE for Windows
NT
group to check that the GPIB Interface Board is correctly installed.
Note
The GPIB card may not work properly if the default IRQ (Interrupt Request)
value for the GPIB card is used for other device in your PC. Changing the IRQ
value for the GPIB card may solve this problem:
1. Run the
I/O Cong
utility
.
2. Select
gpib7 GPIB0
in the
Configured Interfaces
box and click
NNNNNNNNNNNNNNNNNNNNNNNNNN
Edit ...
.
3.
Change the value in the
IRQ Line:
and click
NNNNNNNN
OK
.
4.
Click
NNNNNNNN
OK
to exit the utility
.
The new IRQ value should be carefully selected in order not to aect other
devices in your PC.
Installing Adjustment/P
erformance T
est Program into Y
our PC
1. Make acopy of the program le \E4915 16.EXE" in adirectory of your harddisk drive
.
2. Double-click the lename on the Windows' Filemanager to start extracting the
self-extracting archive.
3. Y
ou will be prompted to enter directory name for installing the program les
. Click [OK] to
use default home directory (
C:\E4915_16 ).
4. Conrm that you get several new directories and les under the designated directory.
