Page 24: Trimode Probe Calibration
Functional Check and Calibration TriMode Probe Calibration After you perform a functional check of the probe, run a probe calibration routine. We recommend that you repeat the probe calibration for all four of the TriMode settings, and do this on each channel that you use. The probe calibration operation minimizes measurement errors by optimizing the gain and offset of both probe attenuation settings on each channel. - Page 25 Functional Check and Calibration Check the Instrument Calibration Status The Calibration Status of the instrument Signal Path Compensation test must be Pass for the probe calibration routine to run. 1. From the Utilities menu, select Instrument Calibration. 2. In the Calibration box, check that the Status field is Pass.

Page 30: Basic Operation
Basic Operation Basic Operation This section includes more information about using the probe controls on the control box and procedures for connecting the probe to your circuit. Attenuation and Input Mode Settings Atten Selection The ATTEN button toggles the probe between the two nominal attenuation settings of 5X and 12.5X. The choice of attenuation setting is a tradeoff between probe dynamic range and noise. - Page 31 Basic Operation Input Mode Selection The Input Mode button toggles the internal probe input selector switches between the four input mode selections. This TriMode feature allows full characterization of a differential signal from a single soldered connection. A-B Mode. The A-B Mode is used for making differential signal measurements and represents the traditional differential probe functionality.
- Page 32 Basic Operation B-GND Mode. The B-GND mode is used for making probe B input single-ended measurements with TriMode probe tips such as the P75TLRST. The P75TLRST probe tip includes a solder connection for the local circuit ground. In the B-GND Mode the P7500 probe input switch is configured to measure the B input relative to this local circuit ground reference.

Page 33: Connecting To A Circuit Board
Basic Operation Connecting to a Circuit Board Use the P75TLRST Long Reach Solder Tip to connect the probe to your circuit. The P75TLRST tip is shipped with the probe and is described below. Other TriMode solder tips are available as optional accessories, as well as a handheld probing module, and are described on the following pages. - Page 34 Basic Operation TriMode Resistor Solder Tips These are optional accessory tips that you can order for your probe. The tips provide solder connection points for the A and B probe input signals at the resistor leads, instead of on the solder tip board.
- Page 35 Basic Operation The dimensions of the solder tip connections are provided here for reference. You can also design the tip footprint into your circuit board layout for easier test connections. To connect the probe tip to your circuit, use the wire and solder that are provided in the wire replacement kit.
- Page 36 Basic Operation Connect the P75TLRST Solder Tip 1. Identify a location where the tip can be placed, soldered, and secured to your circuit. NOTE. You can work with long wires (~1 inch), but keep the finished wire lengths of the signal and ground connections as short as possible.
- Page 37 Basic Operation 4. Attach tip tape to the bottom of the tip. 5. Clean out the tip vias with a solder-wicking material if you are reusing the tip. Thread the wires through the tip. 6. Press the tip to the circuit board and quickly solder the wires to the tip.
- Page 38 Basic Operation Connect the TriMode Resistor Solder Tips Use this procedure to connect both styles of resistor tips to your circuit. 1. Choose a location where the solder tip resistor leads can reach your test points. If you are using a ground connection, note which solder tip ground via is closest to your circuit ground.
- Page 39 Basic Operation 6. Heat the solder tip via and insert the wire. 7. Cut the excess wire on the other side of the solder tip, flush with the board. 8. Cut the ground wire to the length required to reach your circuit ground. Keep the ground wire as short as possible to ensure good performance.
- Page 40 Basic Operation Secure the Tip 11. Push the end of the tip into the probe head until it seats in the probe head. 12. For a secure mechanical connection, use tape or hot glue to secure the tip to your circuit.
- Page 41 Basic Operation Notes on Using the Tips. Use the following precautions when you solder the tips: Use a low-wattage, temperature-controlled soldering iron and a small mass soldering iron tip. The soldering iron temperature should be set as low as possible, while still providing a reliable solder joint. Use SAC305 solder (included with the wire replacement kit) to attach the tip wires to the circuit under test.
