AH 2700A 50 Hz-20 kHz Ultra-precision Capacitance Bridge


AH 2700A 50 Hz-20 kHz Ultra-precision Capacitance Bridge

The AH 2700A offers unparalleled stability, resolution, linearity and accuracy in a multi-frequency capacitance/loss1 bridge (whether manual or automatic). Its numerous state-of-the-art features make it an exceptionally user-friendly instrument. The precision of the AH 2700A is creating new applications in calibration, science, and production in a wide range of fields.

Frequencies: 50, 60, 80, 100, 120, 160, 200, 240, 320, 400, 500, 600, 800 Hz and 1.0, 1.2, 1.6, 2.0, 2.4, 3.2, 4.0, 5.0, 6.0, 8.0, 10, 12, 16 and 20 kHz

Outstanding Features

  • Measures extremely low loss down to a dissipation factor of 1.5x10-8 tan d, a conductance of 3x10-7 nanosiemens or a resistance up to 1.7x106 gigohms
  • As little as 0.4 second required for full precision measurements and as little as 30 ms required for repeated measurements on the same sample
  • Fast analog output has a frequency response of 3 kHz at 3 dB down
  • Negative capacitance and loss ranges measure negative values to allow for unusual samples or three terminal networks
  • Commutation (test signal reversal) to minimize external power line or other periodic signal pickup
  • Three terminal BNC connections minimize connector costs and number of cables
  • IEEE-488 GPIB and IEEE-1174 serial interfaces included; remote device can act as controller or logger
  • Programmability can eliminate the need for an external controller
  • Large, variable-brightness displays having 8 digits for capacitance and loss and 5 digits for frequency
  • Deviation measurements of capacitance, loss or both
  • Zero correction of test fixture capacitance and loss
  • External DC bias up to ±100 volts
  • External trigger capability
  • NIST or NPL traceable calibration
  • Autoranging
  • Automatic internal calibration
  • Self-test diagnostics on power-up and by command
  • Three year warranty
