We know the lan- guage and talk it up with the line operated 610B and bat- tery-powered 601, among others. If you've thought a bout si m pli tying the search for low level currents, our versatile picoammeter line has the instrument for you! Different models offer choices of fast response speed, remote ranging, long- term stability, calibrated zero suppression, low cost. NANOVOLTMETERS, MICROVOLTMETERS AND NULL DETECTORS Holding nanovolt and microvolt level signals is easier when you count on Keithley's line of low noise, highly stable instruments. Most have built-in zero suppression, too! The Models 148 Nanovoltmeter and 147 Nanovolt Null Detector operate by line or battery power. Sensitivi- ties range from the 148's 10 nv or 147's 30 nv, to 100 mv. The low cost 153 measures from .2 μν to 1000 volts, with high ac rejection. For lower cost and proven per- formance, with sub-microvolt resolution, you can count on both our 150A and 149. ac/dc and dc DIFFERENTIAL VOLTMETERS Compare with Keithley! Dc ac- curacies are .01 and .02%. All dc models provide temperature-com- pensated zener references, full input guarding and null sensitivi- ties of 100 μν fs. Included are the .01% accurate 662, with 6-dial readout and the .02% accurate 660A, with 5-dial readout. Plus the .01% accurate 630 featuring a vibrating reed electrometer null detector allowing rated perform- ance with source resistances to 10 10 ohms. The ac/dc 661 high- lights . 0 1 % dc accuracy; .05% ac accuracy over a 10 cps to 80 kc bandwidth. Every model carries a full year guarantee on accuracy. ac AMPLIFIERS If you're amplifying wideband sig- nals, here are 8 dependable ways, spanning 15 cps to 180 mc. Each is an amplifier tuned for either wideband or pulse operation. They feature midband flatness of better than .05%; rise times under 3 nanoseconds and; overload re- coveries within 50 nsec. Models 104 and 105 provide one unity-gain and two xlO amplifiers. The 106 and 107 have three xlO amplifiers. Single decade amplifiers are the 108 and 109. For single unity-gain amplifiers, look for the 110 and 111. • · · · « dc VOLTAGE SUPPLIES For long-term studies, you can rely on Keithley ultra-stable high voltage supplies. Calibrated, in- line dials make output selection quick, easy. Choose ranges up to 5 kv, with either floating or grounded operation. CALIBRATION DEVICES Keithley devices are excellent secondary standards. Our 261 Current Source calibrates and verifies picoammeter accuracy with ranges from 10 5 to 10 14 amperes. Use its voltage twin, the 260, for accurate voltages from 10 10 volt to 1.11 volts. Both devices have 3-dial readout. Both function as sources for zero sup- pression, and both are economi- cally priced, line powered units.
