The 526 provides accurate voltages from ±100nVdc to ±111.1110Vdc to within 20ppm for 1 year, and precise currents from ±10nA to ±111.1110mA to within 50ppm for 1 year. It is an extremely quiet source with <12μVrms of noise measured over a 10Hz to 100kHz bandwidth. DECADE CONTROL Microprocessor assisted decade control allows for continual use of one decade with full carry and borrow capability to and from all more significant decades for easier use and convenient manual operation. Monotonic and linear A/D measurements can be made at any resolution using only one decade control. DISPLAY AND FRONT PANEL CONTROL A user friendly 2-line 40 character display and six front panel decade switches with full carry and borrow allow for fast accurate voltage and current settings. Output settings can be modified using the front panel decade switches and the range keys. Output 2-wire, 4-wire are accomplished with one keystroke or over GPIB/LAN. A crowbar function places the output in a safe mode when desired. The 526 output can be set to 0 volts, allowing the output sense to maintain a true 4-wire low impedance output. RANGES AND RESOLUTION The 526 provides four voltage ranges of 100mV, 1V, 10V and 100V with a resolution of 100nV, 1μV, 10μV and 100μV respectively. Two current ranges provide 10mA and 100mA with a resolution of 10nA and 100nA respectively. NON-VOLATILE MEMORY Up to 32 storage output settings are provided with the 526, that can be recalled at any time. VOLTAGE, CURRENT AND COMPLIANCE LIMITS Selecting voltage and current limits to prevent users from damaging sensitive circuitry or devices under test may be set from the front panel as well as a hardware compliance voltage limit of 120V, 36V, 26V or 16V. APPLICATIONS The 526 is well suited for a variety of applications such as: the design, check and calibration of high speed, high resolution A/D converters; design and certification of high speed data logging and process control systems; calibration of digital voltmeters and multimeters; as an “IMBEDDED STANDARD” and/or simulator; design, testing, simulation and certification of thermocouples, strain gages and transducer instrumentation. It is also a replacement for the Analogic Model 8200.
