Procedures

Performance Verification Procedures

Two types of Performance Verification procedures can be performed on this product: Brief Procedures and Performance Tests. You may not need to perform all of these procedures, depending on what you want to accomplish.
H To rapidly confirm that the oscilloscope functions and was adjusted properly,
just do the brief procedures under Self Tests, which begin on page 1–5. Advantages: These procedures are quick to do, require no external
equipment or signal sources, and perform extensive functional and accuracy testing to provide high confidence that the oscilloscope will perform properly. They can be used as a quick check before making a series of important measurements.
H To further check functionality, first do the Self Tests just mentioned; then do
the brief procedures under Functional Tests that begin on page 1–7. Advantages: These procedures require minimal additional time to perform,
require no additional equipment other than a standard-accessory probe, and more completely test the internal hardware of the oscilloscope. They can be used to quickly determine if the oscilloscope is suitable for putting into service, such as when it is first received.
H If more extensive confirmation of performance is desired, do the Perform-
ance Tests, beginning on page 1–15, after doing the Functional and Self Tests
just referenced. Advantages: These procedures add direct checking of warranted specifica-
tions. They require more time to perform and suitable test equipment is required. (See Equipment Required beginning on page 1–16).
If you are not familiar with operating this oscilloscope, read the TDS 500C,
TDS 600B & TDS 700C Reference (070-9861-XX) or the TDS 500C, TDS 600B & TDS 700C User Manual (070-9869-XX). These contain instructions that will
acquaint you with the use of the front-panel controls and the menu system.

Brief Procedures

Self Tests

The Self Tests use internal routines to confirm basic functionality and proper adjustment. No test equipment is required to do these test procedures.
The Functional Tests utilize the probe-compensation output at the front panel as a test-signal source for further verifying that the oscilloscope functions properly. A probe is required to do these test procedures.
This procedure uses internal routines to verify that the oscilloscope functions and was adjusted properly. No test equipment or hookups are required.

Functional Tests

Brief Procedures
The purpose of these procedures is to confirm that the oscilloscope functions properly. The only equipment required is one of the standard-accessory probes and, to check the file system, a 3.5 inch, 720 K or 1.44 Mbyte floppy disk.
CAUTION. The P6243 and P6245 probes that can be used with this oscilloscope provide an extremely low loading capacitance (<1 pF) to ensure the best possible signal reproduction. These probes should not be used to measure signals exceeding ±8 volts, or errors in signal measurement will be observed. Above 40 volts, damage to the probe may result. To make measurements beyond ±10 volts, use either the P6139A probe (good to 500 volts peak), or refer to the catalog for a recommended probe.
STOP. These procedures verify functions; that is, they verify that the oscilloscope features operate. They do not verify that they operate within limits.
Verify All Input Channels
Therefore, when the instructions in the functional tests that follow call for you to verify that a signal appears on-screen “that is about five divisions in amplitude” or “has a period of about six horizontal divisions,” etc., do NOT interpret the quantities given as limits. Operation within limits is checked in Performance Tests, which begin on page 1–15.
STOP. DO NOT make changes to the front-panel settings that are not called out in the procedures. Each verification procedure will require you to set the oscilloscope to certain default settings before verifying functions. If you make changes to these settings, other than those called out in the procedure, you may obtain invalid results. In this case, just redo the procedure from step 1.
When you are instructed to press a menu button, the button may already be selected (its label will be highlighted). If this is the case, it is not necessary to press the button.

Performance Tests

This section contains a collection of procedures for checking that the TDS 500C, TDS 600B, and TDS 700C Digitizing Oscilloscopes perform as warranted.
The procedures are arranged in four logical groupings: Signal Acquisition System
Checks, Time Base System Checks, Triggering System Checks, and Output Ports Checks. They check all the characteristics that are designated as checked in Specifications. (The characteristics that are checked appear in boldface type under Warranted Characteristics in Specifications).
STOP. These procedures extend the confidence level provided by the basic procedures described on page 1–5. The basic procedures should be done first, then these procedures performed if desired.

Prerequisites

The tests in this section comprise an extensive, valid confirmation of perform­ance and functionality when the following requirements are met:
H The cabinet must be installed on the digitizing oscilloscope. H You must have performed and passed the procedures under Self Tests, found
on page 1–5, and those under Functional Tests, found on page 1–7.
H A signal-path compensation must have been done within the recommended
calibration interval and at a temperature within ±5_ C of the present operating temperature. (If at the time you did the prerequisite Self Tests, the temperature was within the limits just stated, consider this prerequisite met).
H The digitizing oscilloscope must have been last adjusted at an ambient
temperature between +20_ C and +30_ C, must have been operating for a warm-up period of at least 20 minutes, and must be operating at an ambient temperature between +4_ C and either +45_ C for the TDS 600B or +50_ C for the TDS 500C and 700C. (The warm-up requirement is usually met in the course of meeting the Self Tests and Functional Tests prerequisites listed above).
