Specifications

This chapter contains specifications for the DPO4000 and the MSO4000 series
oscilloscopes. All specifications are guaranteed unless noted as "typical."
Typica l spec
Specifications that are marked with the
Ver ification.

All specifications apply to all DPO4000 and MSO4000 models unless noted
otherwise. To meet specifications, two conditions must first be met:

The oscilloscope must have been operating continuously for twenty minutes
within the operating temperature range specified.

You must perform the Signal Path Compensation (SPC) operation described
in the Tektronix 4000 Series Digital Phosphor Oscilloscopes User Manual
prior to evaluating specifications. If the operating temperature changes by
more than 10 °C (18 °F), you must perform the SPC operation again.

Setup + Hold time

Input coupling on clock and data channels must be the same.

For Setup time, positive numbers mean a data transition before the clock.

For Hold time, positive numbers mean a data transition after the clock edge.

Setup + Hold time is the algebraic sum of the Setup Time and the Hold Time programmed by
the user.

For the trigger class width and the trigger class runt, the pulse width refers to the width of the
pulse being measured. The rearm time refers to the time between pulses.

For the trigger class slew rate, the pulse width refers to the delta time being measured. The
rearm time refers to the time it takes the signal to cross the two trigger thresholds again.

NOTE. Completion of the performance verification procedure does not update

the stored time a nd date of the latest successful adjustment. The date and time
are updated only when the adjustment procedures in the service manual are
successfully completed.

The performance verification procedures verify the performance of your
instrument. They do not adjust your instrument. If your instrument fails any of
the performance verification tests, you should perform the factory adjustment
procedures as described in the Tektronix 4000 Series Service Manual.

For the best functionality, you can upgrade the oscilloscope firmware. To upgrade
the firmware, follow these steps:

1. Open up a Web browser and go to www.tektronix.com/software. Use the

The following three conditions must be met prior to performing these procedures:

1. The oscilloscope must have been operating continuously for twenty (20)
minutes in an environment that meets the operating range specifications for
temperature and humidity.

2. You must perform a signal path compensation (SPC). See Signal Path
Compensation in the Tektronix 4000 Series Digital Phosphor Oscilloscopes

3. You mus t c
power circuit. Connect the oscilloscope and test instruments into a common
power strip if you are unsure of the AC power circuit distribution. Connecting
the oscilloscope and test instruments into separate AC power circuits can
result in offset voltages between the equipment, which can invalidate the
performance verification procedure.

The time required to complete the entire procedure is approximately one hour.

move the coaxial cable to the appropriate input on the oscilloscope.

16. Repeat steps 5 through 15, until all channels have been tested.

For the MSO4000 series only, this test checks the threshold accuracy of the digital
channels. This procedure applies to digital channels D0 through D15, and to
channel threshold values of 0 V and +4 V.

1. Connect the P6516 digital probe to t

If using the Wavetek calibrator as the DC voltage source, connect the
calibrator head to the digital channel totest.YouwillneedaBNC-to-0.1inch
pin adapter (Tektronix part number 679-6240-00) to complete the connection.
Be sure to connect the digital channel to the corresponding signal pin and to
