MODEL 202H CHARACTERISTICS
Timing Characteristics
Rep Rate:
0 Hz - 500 kHz at 300 V (1 MHz at lower amplitudes
see Table 2-1).
Delay:
0 ns - 640 s.
Width:
15 ns - 5 ms.
Width Accuracy:
Duplicates 6040 width ±2 ns. Calibrated at 300 V
(50% points). At lower amplitudes width increases
(see Table 2-2).
Duty Factor:
1% maximum at 300 V (higher duty factor at lower
amplitudes-see Table 2-1).
Pulse Separation:
200 ns minimum (between trailing and leading
edges).
Output Characteristics
PULSE OUT
Amplitude:
20 V to 300 V Peak into 50 ohms (Baseline fixed at
ground).
Polarity:
Positive or negative (internally selectable).
Resolution:
2 V.
Linearity:
±1%.
Maximum Power:
18 W average, 1.8 kW peak.
Maximum Current:
6 A peak.
Transition Times:
Leading edge, 5 ns (3 ns typical),
Trailing edge, 10 ns at 300 V (longer at lower
amplitudes-see Table 2-2).
Droop:
0.005%/
s.
Pulse Top Aberrations:
±5% of amplitude (2% typical).
Module Delay:
55 ns typical (between mainframe PULSE OUT and
module PULSE OUT-see Figure 1-1).
Insertion Delay:
100 ns, typical (between mainframe TRIG IN and
module PULSE OUT-see Figure 1-1).
Jitter:
