Specifications

These specifications apply to all TPS2000 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 range. See page 1--8.

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.

H The V/div specifications apply with the probe calibration is set to 1X probe

mode.

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 Performance Verification section.

Accuracy, typical ±51 ppm including all frequency reference errors and ±1 count errors

Frequency Range AC coupled, 10 Hz minimum to rated bandwidth.

Signal Source Pulse Width/ Edge Trigger: all available trigger sources.

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: The oscilloscope counts pul ses 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 relat ively small time.

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

Video Trigger: The Frequency Counter does not operate.
