Speciﬁcations

This chapter contains speciﬁcations for the DPO2000 and the MSO2000 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 DPO2000 and MSO2000 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 prior to evaluating speciﬁcations. (See page 18, Signal Path Compensation (SPC).) If the operating temperature changes by more than 10 °C (18 °F), you must perform the SPC operation again.

eriﬁcation Procedures

NOTE. If your oscilloscope ﬁrmware version is v1.02, it should be updated

before performing the Performance Veriﬁcation procedures. Download the latest ﬁrmware from www.tektronix.com/software.

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) before beginning these procedures. (See page 18, Signal Path Compensation (SPC).) If the operating temperature changes by more than 10 °C (18 °F), you must perform the signal path compensation again.

3. You must connect the oscilloscope and the test equipment to the same AC power circuit. Connect the oscilloscope and test instruments into a common power 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.

Self Test

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

NOTE. The buttons on the oscilloscope toggle the various menu visibilities. If a

menu is not visible, push the respective menu button again.

WARNING. Some procedures use hazardous voltages. To prevent electrical

shock, always set voltage source outputs to 0 V before making or changing any interconnections.

This procedure uses internal routines to verify that the oscilloscope functions and passes its internal self tests. No test equipment or hookups are required. Start the self test with these steps:

1. Disconnect all probes and cables from the oscilloscope inputs.

2. Push the front-panel Default Setup button to set the instrument to the factory

default settings.

3. Push the Utility menu button.
