Programmable Electrometer LOW LEVEL MEASURE & SOURCE Fast, precise current, charge, voltage, and resistance measurements The Model 6514 Electrometer combines flexible interfacing capabilities with current sensitivity, charge measurement capabilities, resolution, and speed that are equal or superior to our earlier electrometers . The Model 6514's built-in IEEE-488, RS-232, and digital I/O interfaces make it simple to configure fully automated, high speed systems for low-level testing The 5%-digit Model 6514 is designed for applications that demand fast, yet precise measurements of low currents, voltages from high resistance sources, charges, or high resistances The Model 6514's exceptional measurement performance comes at an affordable price . While its cost is comparable with that of many high end DMMs, the Model 6514 offers far greater current sensitivity and significantly lower voltage burden (as low as 20/xV) than other instruments can provide R&D on a Budget The Model 6514 offers the flexibility and sensitivity needed for a wide array of experiments, providing better data far faster than older electrometer designs . Applications include measuring currents from light detectors and other sensors, beam experiments, and measuring resistances using a current source In addition to use by researchers in areas such as physics, optics, and materials science, the Model 6514's affordable price makes it an attractive alternative to high end DMMs for low current measurement applications, such as testing resistance and leakage current in switches, relays, and other components . For more information on how the Model 6514 does this, refer to the section titled “Low Voltage Burden .” The Model 6514 builds on the features and capabilities of the Keithley electrometers that preceded it For example, like those instruments, a built-in constant current source simplifies measuring resistance Two analog outputs—a 2V output and a preamp output—are available for recording data with strip-chart recorders ACCESSORIES AVAILABLE A Greater Measure of Confidence • <1fA noise • >200TW input impedance on voltage measurements • Charge measurements from 10fC to20pC • High speed-up to 1200 readings/second • Interfaces readily with switches, computers, and component handlers • Cancels voltage and current offsets easily Ordering Information 6514 Programmable Electrometer Accessories Supplied 237-ALG-2 Low Noise Triax Cable, 3-Slot Triax to Alligator Clips, 2m (6.6 ft) _SERVICES AVAILABLE 6514-3Y-EW 1-year factory warranty extended to 3 years from date of shipment C/6514-3Y-ISO 3 (ISO-17025 accredited) calibrations within 3 years of purchase* TRN-LLM-1-C Course: Making Accurate Low-Level Measurements *Not available in all countries CABLES 237-ALG-2 Low Noise Triax Cable, 3-Slot Triax to Alligator Clips 7007-1 Shielded IEEE-488 Cable, 1m (3.3 ft) 7078-TRX-3 Low Noise Triax Cable, 3-Slot Triax Connectors, 0.9m (3 ft) 7078-TRX-10 Low Noise Triax Cable, 3-Slot Triax Connectors, 3m (10 ft) 7078-TRX-20 Low Noise Triax Cable, 3-Slot Triax Connectors, 6m (20 ft) 8501-1 Trigger-Link Cable, 1m (3 . 3 ft) RACK MOUNT KITS 4288-1 Single Fixed Rack Mounting Kit 4288-2 Dual Fixed Rack Mounting Kit ADAPTERS 7078-TRX-BNC 3-Lug Triax to BNC Adapter 237-TRX-NG Triax Male-Female Adapter with Guard Disconnected 237-TRX-T 3-Slot Male Triax to Dual 3-Lug Female Triax Tee Adapter 237-TRX-TBC 3-Lug Female Triax Bulkhead Connector (1 1kV rated) 7078-TRX-TBC 3-Lug Female Triax Bulkhead Connector with Cap GPIB INTERFACES KPCI-488LPA IEEE-488 Interface/Controller for the PCI Bus KUSB-488B IEEE-488 USB-to-GPIB Interface Adapter

Economical Component Testing Once, electrometers were simply considered too slow to keep up with the high throughput that production test applications demand. The Model 6514 is designed for fast, sensitive measurements, providing speeds up to 1200 readings per second with fast integration or 17 measurements per second with 60Hz line-cycle integration. It offers 10fA resolution on 2nA signals, settling to within 10% of the final value in just 15ms. A normal-mode rejection ratio (NMRR) of 60dB allows making accurate low current measurements, even in the presence of line frequency induced...

LOW LEVEL MEASURE & SOURCE Model 6514 specifications Desired Current Reading: DMM's Actual Current Reading: I = ^SOURCE R VSOURCE ~VBURDEN R Figure 3. Errors Due to Burden Voltage when Measuring with a DMM The example below compares a DMM's voltage burden errors with the 6514's . If: Vsource = 1V R = 50kW 1V The desired current reading is: I = = 20|iA Actual Reading (20|iA range on DMM): Refer to Figure 3. 6514 Actual Reading: VBUrdEn = 10^V Refer to Figure 2. DMM offset Currents Typically, offset currents in DMMs are tens or hundreds of picoamps, which severely limits their low...
