The Agilent 81101A mainframe includes one output channel it generates all the standard pulses and digital patterns needed to test current logic technologies (CMOS, TTL, LVDS, ECL, etc.). Timing values can now be swept without the danger of misleading pulses or dropouts that could cause measurement errors. Specifications. Frequency range: 1 mHz to 50 MHz. Timing resolution: 3.5 digits, 5 ps best case. Period RMS jitter: 0.001% + 15 ps (With PLL), 0.01% + 15 ps (With VCO). Period range: 20 ns to 999.5 s. Period range Accuracy with PLL /VCO: ± 0.01% (±5%) (similar to RMS Jitter). Width range: 10.0 ns to (period - 10.0 ns). Width range Accuracy: ±5% ±250 ps. RMS jitter: 0.01% + 15 ps. Accuracy: ±5% ± 500 ps. Transition time range (10/90): 5 ns to 200 ms variable. Linearity: 3% typ. for transitions > 100 ns. Burst Count: 2 to 65536 (single or double pulses). Delay: Delay, phase or % of period. Double pulse delay: Double pulse and delay are mutually exclusive. Duty cycle: Set between 0.1% and 95% (subject to width limits 99.9% with overprogramming). Output connectors: BNC single-ended. Source Impedance: Selectable 50 ohm or 1 k-ohm. Accuracy: Typ. ± 1%. Max. external voltage: ± 24 V. Short circuit current: ± 400 mA max. Base line noise: 10 mV RMS typ. Overshoot /preshoot /ringing: ± 5% of amplitude ± 20 mV.
