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
