Operation and Service Manual
1 Operation
This operating note provides complete information on the 16048A Test Leads.
The 16048A is shown pictorially in Figure 1-1, its physical dimensions are given
in Table 1-1, and typical characteristics related to offset error are given in Table
1-2. To order additional copies of this operating note, use the option number
listed on www.keysight.com.
Product Description
The 16048A consists of a direct attachment, 4-terminal pair type fixture which
is equipped with four BNC (m) terminated-coaxial test leads. These test leads
are used to attach user-fabricated test fixtures. DC bias levels of up to ±42V
can be applied to the 16048A. Cable length is 1 meter. The 16048A is shown in
Figure 1-1.

Compensation for Fixture Residual Impedance Error
1-
Compensation for Fixture Residual Impedance Error
The 16048A has inherent stray capacitance, residual inductance, and residual
resistance that affect the accuracy of measured values. To compensate for, or
negate, these residuals to minimize measurement error, the instrument’s
Open/Short compensation procedure should be performed. The procedure is
given in the instrument’s operating manual.

Introduction
This chapter gives the service information for the 16048A.
Serial Number for Non-RoHS 16048A:
“MY44100001 – MY44199999” or “SG44100001 – SG44199999”
Serial Number for RoHS 16048A:
“MY44200001 and above” or “SG44200001 and above”.
Maintenance
Shown are the supported parts and their respective RoHS compliant
replacement support part. RoHS conversion involves with design and
dimension change which result in the RoHS support part backward
incompatible with non-RoHS 16048A. Special handling is needed while using
the RoHS replacement part on non-RoHS 16048A. The original support part
number is replaced by the respective “RoHS Compliant Replacement Part”.
Do not disassemble any further than shown. Maintenance consists principally
of cleaning contacts and replacing worn or damaged parts. Take special care
when cleaning contacts. To order parts, use the Keysight Technologies part
numbers listed in Table 2-1. If a faulty part is located in an assembly that
cannot be disassembled, order the next higher assembly or return the whole
device to the nearest Keysight Technologies Sales/Service Office for repair or
replacement.
