7660 Precision LCR Meter

The 7660 LCR meter performs precision impedance measurement over a frequency range of 10 Hz to 2 MHz. The 7660 is a direct replacement for the QuadTech 7600 and IET 7600 Plus. The user interface is almost identical with exception of new features. The SCPI command set is identi- cal to allow the use of existing test programs for control and data col- lection. Features:

  • Frequency range: 10 Hz to 2 MHz
  • 0.05% basic measurement accuracy
  • 7-digit measurement resolution
  • 7.0" TFT, 800×480 color screen
  • Programmable test voltage and current
  • Auto ranging
  • Test setup and measurement data storage
  • Four bnc terminal Kelvin connection
  • Standard interfaces: USB host port, USB Type B, RS-232, Handler, GPIB and LAN
  • Graphical and tabular display of measurements: swept frequency, voltage, and current
  • Sequence testing of up to 6 individual tests
  • Built-in auto-calibration routine

14 Diff erent Impedance Parameters

Measure and display any two parameters simultaneously to achieve coverage and fl exibility. Automated Test Sequencing Run up to six diff erent tests in sequence with a single push of the start button. Each test can have diff erent conditions and limits. Swept Measurements To test how components respond to changes in ac test frequency, voltage, or current, the

7600 Plus meter off ers fast, accurate swept

parameter measurements with results in graphical and tabular format. No complex programming or external control is required. Program and Data Storage Test setups can be stored and recalled from either internal memory or from a standard USB fl ash drive. Measurement data can be stored on a USB fl ash drive in CSV format. Load Correction Substantially improves instrument accuracy by measuring a known standard and applying correction to subsequent measurements. This is ideal for repetitive testing of identical devices under similar conditions. Automated Calibration Procedure The 7660 has a built-in calibration procedure, which can be performed using the SI traceable calibration kit (7000-09). The results and the date of the calibration are stored internally. Ease of Use To ensure that the 7660 is easy to operate, the unit off ers a large color TFT display and a user-friendly, menu-driven interface.
