Page 13: Features And Accessories
Features and Accessories The P5120 is a passive high-voltage probe designed for use with TPS2000 series instruments. The probe features a floating reference and is ideal for measuring and troubleshooting power supplies and high-voltage devices. The probe provides 20X attenuation of signals up to 1000 V and derated performance up to 200 MHz. - Page 14 Features and Accessories P5120 features and standard accessories (Cont.) Compensation Box - - The compensation box contains low- and high-frequency compensation adjustments. The high-frequency adjust- ments are accessible by removing the compensation box cover. Refer to Adjustment Procedures on page 7.
- Page 15 The hook tip will firmly hold the conductor under test. Reference Leads - - The P5120 probe comes with a long and a short, floatable reference lead. Both reference leads connect to a removable crocodile clip.
- Page 16 Reference WARNING. Do not connect the Probe-to-BNC Adapter to a floating or high-voltage source. The BNC adapter is only rated to 500 V (DC + peak AC) with the probe reference connected to earth ground. P5120 High-Voltage Probe Instructions www.valuetronics.com...

Page 17: Operating Basics
Maximum Nondestructive Input Voltage The P5120 probe is designed to be used in a high voltage environ- ment; however, the voltage input rating of the probe starts to decrease at about 2 to 3 MHz. Please refer to the Specifications section of these instructions for the maximum input voltage and frequency derating information. -
Page 18: Probe Loading
Refer to Figure 12 on page 21 for a graph of frequency versus input impedance. The probe has virtually no loading effect on sources with relatively low impedance and low frequency. P5120 High-Voltage Probe Instructions www.valuetronics.com... -
Page 19: Adjustment Procedures
Adjustment Procedures The low-frequency (LF) compensation of the P5120 probe must be checked every time the probe is connected to a different oscilloscope input. The high-frequency (HF) compensation should be checked if the probe was repaired or fails to meet rated bandwidth specifications. -

Page 27: Performance Verification
Performance Verification Use the procedure in this section to verify that the P5120 probe meets the warranted bandwidth specification highlighted with boldface type in the Specifications section on page 19. The steps of this procedure must be performed in the order given using a TPS2000 series instrument and other equipment that meets the minimum requirements listed in Table 1. -

6. Note that the frequency is greater than 200 MHz for the TPS2024 and 100 MHz for the TPS2012 and 2014. If not, repeat the HF compensation to achieve a faster risetime. P5120 High-Voltage Probe Instructions www.valuetronics.com... -
Page 29: Maintenance
Maintenance This section contains information necessary for the maintenance and repair of the P5120 probe. NOTE. The P5120 probe has no replaceable components. Accessory parts may be ordered as indicated in the replaceable parts list. Cleaning Instructions Clean the probe using a soft cloth dampened with a mild detergent and water solution. -

2. Put the probe into a plastic bag or wrap to protect it from dampness in transit. 3. Place the probe into the box and stabilize it with light packing material. 4. Seal the carton with shipping tape. P5120 High-Voltage Probe Instructions www.valuetronics.com... -
Page 31: Specifications
Specifications that are not warranted are typical (Tables 3 and 4) and are provided as general information for your convenience. The specifications apply to a P5120 probe installed on a Tektronix TPS2000 series oscilloscope. The instrument must have a warm-up period of at least 20 minutes and be in an environment that does not exceed the limits described in Table 5. -
