. The following waveforms from the NSP were
measured using:
•
An isolated/floating Tektronix DPO 2024 Digital Phosphor Oscilloscope
•
Pearson Current Monitor 6585 with 50 Ω terminator – 0.5 V/A
•
Tektronix THDP0100 High Voltage Differential Probe, or
•
Tektronix P6015A High Voltage Probe
Oscilloscope traces showing typical output waveforms of the NSP are shown below.

Internal Voltage Divider Waveforms
In this example, the High Voltage Differential Probe was connected across the middle resistor of R
p
(voltage division ratio 1:4.5, not user accessible) with a high impedance load. In the next section, this will
be compared to a capacitive voltage divider output. These traces illustrate the output waveforms that a
user can expect to see when driving high impedance loads.
