RLC Digibridge
- 0.1% accuracy for R, L, and C
- Automatic limit comparison and binning
- Two test frequencies (1 kHz and 120 Hz)
- IEEE bus/handler option
- External DC bias capability
- Full-digit, dual displays
- Built-in Kelvin test fixture
Measurement Parameters and Modes: Series or parallel R and Q,
series or parallel L and Q, series or parallel C and D. Continuous-repetitive,
single, or averaged (set of 10) measurements; start button initiates single or averaged
measurements. Keyboard selection of these and all measurement conditions.
Main Displays (3 selections): Value display is LED-type
numerical readout with automatically positioned decimal points and illumination of units;
five digits for RLC (99999) and simultaneously four digits for DQ (9999). Limits display
shows comparator bin limits and nominal values. Bin No. display shows the bin
assignment of the measured device.
Measurement Rates: Approximately 2, 3, and 7
measurements/second. Keyboard selections are: "slow, medium, fast."
Test Frequencies: Keyboard selection between 2. Actual
frequencies: 120.00 Hz and 1020.0 Hz.
Ranges: Automatic ranging for best accuracy; autorange can be
inhibited by keyboard selection. Three basic ranges of 2 decades each, for each
parameter. Automatic extensions to min and max, as tabulated.

Bias: Connector for external voltage source, on-off switch, and
indicator for light. Limit, 60 V (max). External source requirements: ripple
< 1 mV pk-pk, dynamic Z << 1W with currents of ± 50
mA pk (source and sink); external discharge circuit recommended.
Supplementary Display: Parameters, modes, overrange and
underrange conditions, range held, bias on, and remote control.
Sorting: Limit comparator sorts vs a DQ limit and up to 8 pairs
of RLC limits into 10 bins, conveniently defined by keyboard entries. GO/NO GO is
indicated, whether bin number of measured value is selected as main display. |
