For example, if you measured 50.13 mV, then the CF = 50/50.13 = 0.997. The correction factor will be used in step 14 of this procedure to calculate the corrected amplitude, V corr P5100A & P5150 High Voltage Probes Technical Reference... - Page 15 If your probe does not meet the specification, service-level adjustments (DC gain and high-frequency compensation) may be required. (See page 5, P5100A Adjustments.) The procedures to make adjustments and to optimize the bandwidth and high frequency response must be done by a qualified service technician.

Page 19: Dc Gain And High Frequency (Hf) Compensation
To perform the high-frequency compensation adjustment you will need a signal source that has all of the following characteristics: Fast rise output with rise time ≤500 ps Output properly terminated The Picosecond Labs 2600C Pulse Generator output meets these requirements when properly terminated. P5100A & P5150 High Voltage Probes Technical Reference... - Page 20 5. Adjust the DC gain (R9) to a probe output level of 5 V, ±0.088 V, as displayed on the oscilloscope. 6. Record the output level in the outgoing column of the System DC Attenuation Accuracy check in the test record. P5100A & P5150 High Voltage Probes Technical Reference...

Set the oscilloscope to: vertical to 1 V/division horizontal to 4 ns/division averaging to 64 input impedance to 1 MΩ 4. Adjust the HF response as follows: P5100A & P5150 High Voltage Probes Technical Reference...
- Page 23 Adjust R2 for the last ~5 ns. If the overshoot is too great, then adjust R2 to roll off the front corner and readjust R3 followed by R1. The procedure is done when the 3 adjustments have been optimized for the best overall response. 5. Reassemble the probe. (See page 12, Reassemble the Probe.)

Nine digit part numbers (xxx-xxxx-xx) are Tektronix part numbers P5150 probes are intended for use with oscilloscopes that have isolated (floating) inputs. The Tektronix TPS2024B and THS3024 oscilloscopes are the highest bandwidth floating-input oscilloscopes currently available. If you do not have access to one of these oscilloscopes, use the recommended ground-referenced model. - Page 26 Use C2 for a coarse LF adjust and use C116 to get a consistent roll up or roll off. Finally, go back and use C2 one last time to flatten the overall response. 2. Proceed to the High Frequency (HF) Adjustment. (See page 15, High Frequency (HF) Adjustment.)

- Page 27 P5150 Adjustments High Frequency (HF) Adjustment 1. Connect the probe and equipment as shown in the High Frequency (HF) Adjustment setup for the P5100A probe. (See Figure 9 on page 10.) 2. Set the oscilloscope horizontal to 4 ns/div. (Adjust the oscilloscope as necessary to view the leading edge of the waveform.)
