Product End-of-Life Handling

Components that Contain Mercury. The cold cathode fluorescent tube located in the liquid crystal display backlight contains trace amounts of mercury. When you are ready to reclaim the oscilloscope, you must properly transfer it according to local regulations concerning mercury-containing equipment, or ship the oscilloscope to the Tektronix Recycling Operations (RAMS). You can contact Tektronix for the RAMS shipping address and instructions.

H The oscilloscope must have been operating continuously for ten 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.

Not Equal: If the pulse is narrower than the specified width, the trigger point is the trailing edge. Otherwise, the oscilloscope triggers when a pulse continues longer than the time specified as the Pulse Width.

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.

t ≤ 165 ns: guardband = ±16.5 ns

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 signifi cant 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.

EN 61000--3--2, AC power line harmonic emissions

Australia/New Zealand Meets the i ntent of Australian EMC Framework as demonstrated to the following specification:

AS/NZS 2064.1/2

U.S.A. Emissions comply with FCC Code of Federal Regulations 47,

Part 15, Subpart B, Class A Limits

Emissions that exceed the levels required by this standard may occur when this equipment is connected to a test object.

To ensure compliance to the standards listed above, attach only high quality shielded cables to this oscilloscope. High quality shielded cables typically are braid and foil types that have low impedance connections to shielded connectors at both ends.

The increase in trace noise while subjected to a test field (3 V/m over the frequency range 80 MHz to 1 GHz, with 80% amplitude modulation at 1 kHz) is not to exceed 2 major divisions peak--to--peak. Ambient conducted fields may induce triggering when the trigger threshold is offset less than 1 major division from ground reference.

The increase in trace noise while subjected to a test field (3 V/m over the frequency range 150 kHz to 80 MHz, with 80% amplitude modulation at 1 kHz) is not to exceed 1 major division peak--to--peak. Ambient conducted fields may induce triggering when the trigger threshold is offset less than 0.5 major divisions from ground reference.
