Condensed Specifications (Contact XiTRON for complete specifications.) VOLTAGE INPUTS Amplitude: 0.05% + 0.005%/kHz for any single input and for matching between any inputs multiply by 2 for voltages in excess of 300Vpk Phase: 0.05° + 0.005%/kHz between A and B on same range, + 0.0025°/kHz per range when differing ranges, + 0.05°/kHz between unpaired inputs, multiply by 2 for voltages in excess of 300Vpk Noise: 20nV + 0.00001% of full-scale range/√Hz of measurement bandwidth DC Offset: 100μV + 0.03% of full-scale range Distortion: -80dB at any harmonic Voltage Range: 10mV to 1000Vpk full scale (10Vrms max for 50Ω input) in 3:1 steps. Fixed or auto range Trigger Level: Zero, TTL, ECL, CMOS, or Variable. 1% of input range accuracy Bandwidth: >2.5MHz or user-defined upper limit in the range of 5Hz to 100kHz (-3dB) Configuration: Balanced Differential BNC input pairs with separate Guard binding posts. DC + AC or AC only coupling (0.1Hz cut off). Guard may be externally driven or internally connected to either input Lo Impedance: 600kΩ to Guard from each input node, selectable 50Ω input impedance, in parallel with less than 35pF Common Mode: Guard isolated from ground (100MΩ | | 1000pF) for voltages <1000Vpk. Inputs may have voltages to Guard of up to the larger of the range full-scale value or 10V. CMRR referred to Guard is >80db for frequencies up to 10kHz, decreasing linearly to >60dB at 100kHz. CMRR referred to ground is >140dB at DC to 10kHz, decreasing linearly to >100dB at 100kHz CURRENT INPUTS Current inputs are as voltage inputs with an internal current shunt, yielding full-scale current ranges of up to 300mA peak in 3:1 steps. Maximum burden is 250mV External shunts may optionally be used on the voltage inputs to extend the current ranges up to 20A RMS PHYSICAL Power: 80 – 265 Vrms autoselect, 40 – 400 Hz @ 25VA max Size: 7”h x 17”w x 14”d Weight: 20 lbs Operating Range: 0°C to 50°C, less than 85% RH at 40°C (non-condensing) Storage Range: -30°C to +65°C, less than 95% RH at 40°C (non-condensing) WARRANTY Two Years ORDERING INFORMATION PART # DESCRIPTION 822-6250 Two-Input Phase Angle Voltmeter 822-AIO 12 Channel Analog Output, 16 ChannellDigital Output RE Rack Adapter Kit UG6250 Additional 6250 Operating Manual All 6250 instruments have IEEE488, RS232 and Parallel Printer Interfaces as standard.
