The HP 4193A can measure and display impedance magnitudes from 10 mOhm to 120 kOhm. Impedance phase is displayed from + 180.0 to -180.0. Accuracy is as good as 3.0 percent of reading (magnitude) and 3.2 degrees (phase).
Also, the HP 4193As 3.5-digit resolution makes it easy to see small changes in measurement results during adjustment procedures.
When you are testing complex components such as ceramic resonators, its useful to sweep frequency to get the big picture, and to identify such critical impedance points as the series resonant point. This requires both swept measurement and measurements at individual spot frequencies. The HP 4193A can do both.
The HP 4193A can be tuned to any individual frequency from 400 kHz to 110.0 MHz with a maximum resolution of1 kHz. If a greater frequency resolution is required, it can be provided by connecting an external synthesized source such as the HP 3335A or HP 8656B to the HP 4193A EXT OSC input.
Flexible internal frequency sweep is an exciting HP 4193A feature. Frequency can be swept linearly over any portion of the HP 4193A frequency range or swept logarithmically over the entire 400 kHz to 110.0 MHz range.
Several test fixtures help adapt the HP 4193A to your device under test. For example, the handy L-ground probe is useful for in-circuit testing. The HP 16099A Test Fixture Adapter and three associated fixtures help connect to out-of-circuit devices of various sizes and shapes.
