   KEITHLEY 197   Description / Specification:    
KEITHLEY 197 Autoranging µV Digital Multimeter

The Keithley 197 combines 5 1/2 -digit resolution (on a 220,000-count display) with 1 uV, 1 nA, 1 m-ohm sensitivity. Basic dcV accuracy is 0.011 %. The 197 also has extended performance features. Measure voltage over 9 decades from 1 uV to 1000V. Input resistance on the two lowest voltage ranges exceeds 1 G-ohm. TRMS ac measurements can be made to 100kHz. Make 2- or 4-terminal ohms measurements over 11 decades from 1 m-ohm to 220 M-ohm. Six current ranges measure from 1 nA to 10 A. The microprocessor-based 197 is loaded with smart features . Display annunciators indicate the measurement mode and units. Autoranging on V, ohms, and dB automatically displays maximum resolution. Audio and communication circuit analysis is easy with direct-reading dB measurements referenced to 600 ohm. Resolution is 0.01 dB above 1 mV. Pushbutton relative reference (REL) nulls out or zeros on-range readings. The DATA LOGGER stores up to 100 readings at 6 automatic rates from 3 per second to 1 per hour, or manually at the touch of a button. Specifications.

Averaging is a mathematical process to reduce the variation in a measurement by summing the data points from multiple measurements and dividing by the number of points summed.

Fall Time
Fall time is the time required for the amplitude of a pulse to decrease (fall) from a specified value (usually 90 percent of the peak value exclusive of overshoot or undershoot) to another specified value (usually 10 percent of the maximum value exclusive of overshoot or undershoot).

Noise Density
Noise Density is the amount of noise within a defined bandwidth, usually normalized to 1 Hz.

Resolution Bandwidth (RBW)
Resolution Bandwidth (RBW) is the minimum bandwidth over which you can separate two signals and still see them.
