Installation Installation Connecting to the Host Instrument WARNING. Your TekVPI instrument may require a firmware upgrade to support full functionality of the TDP0500 and TDP1000 probes. Before you connect the probe, check the version requirements. (See page 45, Host Instrument Firmware.) 1. Slide the probe into the TekVPI receptacle. The probe snaps when fully engaged. When you connect the probe, the host instrument reads information from the probe and identifies the probe type. 2.
Installation Probe Controls and Indicators Range Button and LEDs When the probe is powered on, all LEDs briefly light during the power-on self test routine, and then one of the Range LEDs remains lit. This indicates that the probe is in normal operating mode. Press the Range button to toggle the range selection. The corresponding LED lights to indicate the selected range. NOTE. The host instrument sets all probe settings to the last known state for the probe/channel combination.
Installation Bandwidth Limit Button and LEDs Press the Bandwidth Limit button to select one of four limit values. The corresponding LED lights to indicate the selected bandwidth limit. When no LED is lit, the probe is operating at full bandwidth.
Installation DC Reject Button Press the DC Reject button to eliminate the DC component of the measured signal from the output of the probe. The LED lights to indicate that the DC Reject is enabled. DC reject is useful when you are measuring small amplitude signals superimposed on a large differential offset component. DC reject generates an internal offset that cancels the DC component of the signal.
Installation Menu Button 1. Press the probe Menu button to display the Probe Control screen on the oscilloscope. NOTE. Probe menu screens vary slightly between oscilloscope series; DPO7000 Series screens are shown here. This screen includes controls for probe functions that are not accessible on the probe, such as AutoZero and Offset. Other functions, such as Bandwidth Limit, can be controlled from both locations. 2. Use the touch-screen buttons on the instrument to set the probe parameters. 3.
Functional Check Functional Check Use the following procedure to check that your probe is functioning properly. If you want to verify that your probe meets the warranted specifications, refer to the Performance Verification procedures in the TDP0500 & TDP1000 Probes Technical Reference Manual. Required Equipment Description and quantity Performance requirement Recommended example 1 Oscilloscope TekVPI Interface Tektronix DPO7000 Series Y-lead adapter 0.
Functional Check Signal 1. Connect the probe to any channel of the oscilloscope and set the oscilloscope to display that channel. 2. Use the Y-lead Adapter and two SMT KlipChips to connect the probe tip to the PROBE COMP terminals on the oscilloscope. 3. Press AUTOSET (or adjust the oscilloscope) to display the calibration waveform. A stable waveform indicates that your probe is functioning properly.
Calibration Calibration The probe calibration routine minimizes your measurement errors by optimizing the gain and offset of the probe and oscilloscope combination. We recommend that you repeat the probe calibration on each channel that you use. Individual calibration constants are stored for each probe on each channel. NOTE. Probe calibration functions are not available on all oscilloscope models.
Calibration Test Procedure Check the Calibration Status of the instrument: 1. From the Utilities menu, select Instrument Calibration. 2. In the Status box, check that pass is displayed. 3. If the Instrument Calibration Status is not pass, run the Signal Path Compensation routine: Disconnect all probes and signal sources from the oscilloscope, and select Calibrate. When pass displays in the status box, proceed to the next step.
Calibration 4. Connect the probe to the oscilloscope PROBE COMP connector. 5. From the Vertical menu, select Probe Cal.
Calibration 6. When the Probe Setup screen appears, select Clear ProbeCal, and then select Calibrate Probe. The probe calibration routine begins. When the routine completes, a notifier appears. Close the notifier and begin using your probe.
Basic Operation Basic Operation Follow these operating guidelines to get optimum performance from your probe. Probe Head Assembly The probe head is designed for ease of use and high performance. Its small size makes it easy to handle in tight areas. 1. The probe tip sockets are sized to press onto two 0.025 inch pins spaced 0.100 inch apart. 2. The ground socket provides a short ground path for ground connections. Most differential measurements do not require a ground connection, however.
Basic Operation Probe Input The probe is electrically protected against static voltage. However, if you apply voltages above its design limits you may damage the probe tip amplifier. The limits are shown in the 4.25 V and 42 V range graphs on the following pages. (See Figure 2 on page 17.) (See Figure 3 on page 18.

Basic Operation Figure 3: Dynamic and Offset Limitations, 42 V Range 18 TDP0500 & TDP1000 Quick Start User Manual
Basic Operation Probe Offset and AutoZero The probe offset is adjustable to permit operation within the linear range of the probe and to increase the sensitivity of the probe at higher DC measurement voltages. The AutoZero routine eliminates DC offset errors (drift) in the probe signal path, and aligns the offset value of the probe to the oscilloscope.
Basic Operation Offset To set the probe offset, follow these steps: NOTE. See your oscilloscope manual for specific instructions on using the offset control. 1. Use the vertical position control to set a zero reference level on the oscilloscope display. 2. Verify that the DC Reject LED on the probe is not lit (the oscilloscope coupling is set to DC).
Basic Operation 3. Attach the probe to the circuit. 4. Adjust the offset to bring the trace to the oscilloscope zero reference. 5. If you change the volts/division setting, adjust the offset to keep the trace on the zero reference level. NOTE. The probe has two linear operating ranges: ±4.25 V and ±42 V. The offset range is ±42 V for both operating ranges.

Probing Principles Probing Principles Read the helpful hints on the following pages to make probing easier and noise free. Probe Grounding In addition to the (+) and (-) inputs on the probe head, there is also a ground (common) input. You can use the probe to take a differential measurement regardless of whether the ground is connected. CAUTION. To avoid damaging the circuitry under test, connect the probe ground (common) to a ground-reference point only.
Probing Principles Input Impedance and Probe Loading When you connect the probe inputs to a circuit, you are introducing new resistance, capacitance, and inductance into the circuit. Each input of the differential probe has a characteristic input impedance of 500 kΩ to ground in parallel with less than 2 pF. For signals with low source impedance and frequency, the 500 kΩ input impedance on each input is large enough to prevent the inputs from loading the signal sources.
Maintenance Maintenance This section contains maintenance and support information for your probe. Host Instrument Firmware Some instruments may require a firmware upgrade to support full functionality of the TDP0500 and TDP1000 probes. Instruments with lower version firmware may not display all probe controls and indicators on screen, and in some cases may require you to power-cycle the instrument to restore normal instrument operation.
Maintenance Replacement Parts There are no user-replaceable parts within the probe. Refer to the accessory list for replaceable accessories for your probe. Cleaning Protect the probe from adverse weather conditions. The probe is not waterproof. CAUTION. To prevent damage to the probe, do not expose it to sprays, liquids, or solvents. Avoid getting moisture inside the probe during exterior cleaning. Do not use chemical cleaning agents; they may damage the probe.
