Quan-Tech 315C Resistor Noise Test Set
The Quan-Tech 315C Resistor Noise Test
Set is designed to meet the needs of the laboratory,
Q.A., and production departments. The 315C contains
a processor to compute the applied voltage, the
INDEX value, and the correction factor for low noise
resistors. Faster and easier to operate, yet more
versatile with data logging and programming over an IEEE-488 bus.
Features:
-
Measurement Time - less than 1 second.
-
Resistance Range - 1 ohm to 100 megohms.
-
Ohmmeter - the resistance is measured
and displayed.
-
Applied Voltage - the required voltage
for the programmed wattage is calculated and
displayed.
-
Noise Index - the INDEX is calculated
and displayed including the correction factor
for low noise resistors (normal mode).
-
Channel Select - up to 99 resistor
selections available for resistor network
analysis with a remote test station.
-
Processor Controlled IEEE-488 Bus -
instrument programming and data logging over the bus.
-
Industry standard
-
Meets requirements of MIL-STD-2O2B
-
1 ohm to 100 megohms
-
IEEE-488 interface
-
Discrete or resistor network scanning
-
No lookup tables required
Applications:
The ever increasing demand for greater
sensitivity, resolution, product uniformity, and
reliability requires careful attention to all
circuit elements. The QuanTech 315C has been
engineered to simplify the research, development,
and product control of resistors and resistor
networks. Since the current noise of resistor is a
function of the current density it is a measure of;
-
the noise quality and uniformity of the
film;
-
the quality of the trimming process,
-
the quality of the end terminations,
-
and any bridging of the resistor paths.
