HP 4349B 4-Channel High Resistance Meter with Option 001 ( 2 channels )

Getting Started 1-1

HP 4349B

Overview

The HP 4349B 4-Channel High Resistance Meter is a high throughput, digital high resistance

meter. The HP 4349B is designed for production testing of capacitors.

Features

Designed for capacitor measurements

4-channel input

High speed measurement

Fast settling time

High speed contact check

Comparator function

High Throughput

To verify component reliability, capacitor manufacturers need to test capacitor insulation

resistance at dierent voltage levels. The 4-channel conguration permits simultaneous

testing of four capacitors with dierent test voltages. This testing technique reduces the

investment cost for instruments to 25% when compared to a single channel instrument. The

HP 4349B's 11 ms 4-channel simultaneous measurement improves the test throughput on

capacitor production lines.

When insulation resistance testing for capacitor manufacturers, capacitor charge time is a

key factor in slowing down measurement speed. The HP 4349B's front-end has a 1 k input

resistance to reduce the capacitor's charge time, and thus increases test throughput.

The contact check function veries that the signal path between the handler and the DUT

is optimal for a measurement. Contact checking maintains automatic handler/DUT integrity

while keeping system throughput high.

System Integration

Built-in comparators for all four channels and the HP-IB/handler interface make system

integration with automatic handlers and computers a fast and clean process

Note

The HP 4349B has no test voltage source so an external voltage source is

.

required to make resistance measurements. (The HP 4349B converts current

measurement data into resistance using the test voltage data entered into

memory.)
