Test application parameters
You must enter test parameters that are consistent with the following values. Otherwise, you may
receive unsettled and inaccurate measurements.
The Potential Pulse and Square Wave test application parameters are listed below:
Model 2450-EC
• Peak potential: -20 V ≤ Epeak ≤ +20 V
• Base potential: -20 V ≤ Ebase ≤ +20 V
• Current measure ranges: 1 μA, 10 μA, 100 μA, 1 mA, 10 mA, 100 mA, 1 A
• Source limit (compliance): 105 % of selected current range
• Pulse period and width:
• Current measure range = 1 μA
• 200 ms ≤ period ≤ 3600 s
• 100 ms ≤ pulse width ≤ (0.99 × period)
• Current measure range > 1 μA
• 4 ms ≤ period ≤ 3600 s
• 2 ms ≤ pulse width ≤ (0.99 × period)
• Sample time:
• Minimum is 166.667 µs
• Maximum is lesser of 166.667 ms and (pulse width - 1 ms)
• Number of cycles: 1 to 100,000
