Specifications

These specifications apply to all TDS1000- and TDS2000-series oscilloscopes. To verify that an oscilloscope meets specifications, it must first meet the following conditions:

H The oscilloscope must have been operating continuously for twenty minutes

within the specified operating temperature.

H You must perform the Do Self Cal operation, accessible through the Utility

menu, if the operating temperature changes by more than 5 °C.

H The oscilloscope must be within the factory calibration interval of one year.

Specifications begin in Table 1--1. All specifications are guaranteed unless noted “typical.” Specifications that are marked with the n symbol are checked in the chapter Performance Verification.

Less than: The trigger point is the trailing edge.

Greater than (also called time-out trigger): The oscilloscope triggers when a pulse continues longer than the time specified as the Pulse Width.

Trigger Frequency Counter

Signal Source Pulse Width or Edge Trigger modes: all available trigger sources

The Frequency Counter measures trigger source at all times, including when the oscilloscope acquisition is halted due to changes in the run status, or acquisition of a single shot event has completed.

Pulse Width Trigger mode: The oscilloscope counts pulses of significant magnitude inside the 250 ms measurement window that qualify as triggerable events, such as narrow pulses in a PWM pulse train if set to < mode and the width is set to a relatively small time.

Edge Trigger mode: The oscilloscope counts all edges of sufficient magnitude and correct polarity.

Video Trigger mode: The Frequency Counter does not operate.

Pollution Degree

Descriptions

Test and measuring equipment.

A measure of the contaminates that could occur in the environment around and within a product. Typically the internal environment inside a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.

H Pollution Degree 1. No pollution or only dry, nonconductive pollution

occurs. Products in this category are generally encapsulated, hermetically sealed, or located in clean rooms.

H Pollution Degree 2. Normally only dry, nonconductive pollution occurs.

Occasionally a temporary conductivity that is caused by condensation must be expected. This location is a typical office/home environment. Temporary condensation occurs only when the product is out of service.

H Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution

that becomes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.

H Pollution Degree 4. Pollution that generates persistent conductivity through

conductive dust, rain, or snow. Typical outdoor locations.
