CompactPCI digitiser offers 14-bit resolution
The GaGe CompuScope 14100C from TTi (Thurlby Thandar Instruments), is a 6U form factor CompactPCI digitiser card that can sample analogue signals at speeds of up to 100 MS/s (megasamples per second).
Five different test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHZ and 100 kHz (SR720 only), three preset voltage levels, internal and external capacitor biasing and three different measurement speeds allow unmatched flexibility to create the correct test environment.
The convenient auto-measure mode simplifies measuring unknown parts by automatically calculating the best part model and range for any component.
Capacitor measurements use either the internal 2.0 V DC bias or an external DC source of up to 40 V.
Stray impedances are removed from measurements with a simple, fast null calibration procedure.
The built-in Kelvin fixture handles radial-lead components, and adaptors are included for axial components.
Optional fixtures include SMD tweezers, Kelvin clips and BNC adaptors.
Built-in binning sorts components into overlapping or sequential bins.
Up to nine complete instrument configurations may be saved to non-volatile memory for quick set-up.
For easy integration with computerised test environments, an RS-232 interface is standard, with optional IEEE-488 and handler interfaces.
Measurement modes are Auto, R + Q, L + Q, C + D and C + R, with series or parallel equivalent circuits.
The display indicates the parameter value, deviation, percentage deviation or bin number.
Deviation and percentage deviation are calculated relative to a stored value.
Measurement ranges are 0.0001 ohm to 2000 megohm for resistance, 0.0001 æH to 99999 H for inductance and 0.0001 pF to 99999 æF for capacitance.
Q can be measured between 0.00001 and 50 and D between 0.00001 and 10.
Basic accuracy is 0.20% for the SR715 and 0.05% for the SR720.
