Andeen-Hagerling AH 2700A Overview

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

Features:

• Frequency: kHz, 0.1, 1, 10
• Accuracy: ppm, ±9, ±5, ±11
• Stability: ppm/year, ±<1.9, ±<1.0, ±<1.9
• Temperature Coefficient: ppm/°C, ±0.07, ±0.035, ±0.07
• Resolutions: af/pm, 16/0.8, 0.8/0.16, 2.4/0.5
• 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
