15 | Keysight | 4285A Precision LCR Meter – Data Sheet
Correction Functions
Zero open
Eliminates measurement errors due to parasitic stray admittance (C, G) of the test
fixture.
Zero short
Eliminates measurement errors due to parasitic residual impedances (L, R) of the test
fixture.
Load
Improves the measurement accuracy by using a device whose value is accurately known
(a working standard) as a reference.
List Sweep
A maximum of ten frequencies or test signal levels can be programmed. Single or
sequential tests can be performed. When Option 4285A-001 is installed, DC bias
voltages can also be programmed.
Comparator Function
Ten-bin sorting for the primary measurement parameter, and IN/OUT decision output for
the secondary measurement parameter.
Sorting modes
Sequential mode. Sorting into unnested bins with absolute upper and lower limits.
Tolerance mode. Sorting into nested bins with absolute or percent limits.
Bin count
0 to 999999
List sweep comparator
HIGH/IN/LOW decision output for each point in the list sweep table.
Other Functions
Store/Load
Ten instrument control settings, including comparator limits and list sweep programs,
can be stored and loaded into and from the internal nonvolatile memory. Ten additional
settings can also be stored and loaded from each memory card.
GPIB
All control settings, measured values, comparator limits, and list sweep program can be
controlled or monitored. Uses ASCII and 64-bit binary data format. GPIB buffer memory
can store measured values for a maximum of 128 measurements and output packed
data over the GPIB bus. Complies with IEEE-488.1 and 488.2. The programming
language is Test and Measurement Systems Language (TMSL).
GPIB interface functions
SH1, AH1, T5, L4, SR1, RL1, DC1, DT1, C0, E1
Self test
Softkey controllable. Provides a means to confirm proper operation.
Option 4285A-001 (Internal DC Bias)
Adds the variable DC bias voltage function.
