General Safety Summary
|
Review the following safety precautions to avoid injury and prevent damage to |
|
this product or any products connected to it. To avoid potential hazards, use this |
|
product only as specified. |
To Avoid Fire or Personal |
Use Proper Power Cord. Use only the power cord specified for this product and |
Injury |
certified for the country of use. |
|
Connect and Disconnect Properly. Connect the probe output to the measurement |
|
instrument before connecting the probe to the circuit under test. Disconnect the |
|
probe input and the probe ground from the circuit under test before disconnecting |
|
the probe from the measurement instrument. |
|
Ground the Product. When operating with AC power, this product is grounded |
|
through the grounding conductor of the power cord. To avoid electric shock, the |
|
grounding conductor must be connected to earth ground. Before making |
|
connections to the input or output terminals of the product, ensure that the |
|
product is properly grounded. |
|
When operating with battery power, this product must still be grounded. To |
|
prevent electric shock, always connect a grounding wire between the ground |
|
terminal on the rear panel and earth ground. |
|
Observe All Terminal Ratings. To avoid fire or shock hazard, observe all ratings |
|
and markings on the product. Consult the product manual for further ratings |
|
information before making connections to the product. |
|
Connect the ground lead of the probe to earth ground only. |

Preventing Electrostatic Damage
CAUTION. Electrostatic discharge (ESD) can damage components in the oscilloscope and its accessories. To prevent ESD, observe these precautions when directed to do so.
Use a Ground Strap. Wear a grounded antistatic wrist strap to discharge the static voltage from your body while installing or removing sensitive components.
Use a Safe Work Area. Do not use any devices capable of generating or holding a static charge in the work area where you install or remove sensitive components. Avoid handling sensitive components in areas that have a floor or benchtop surface capable of generating a static charge.
Handle Components Carefully. Do not slide sensitive components over any surface. Do not touch exposed connector pins. Handle sensitive components as little as possible.
Transport and Store Carefully. Transport and store sensitive components in a static-protected bag or container.

Specifications
Specifications
This appendix contains specifications for the TDS3000B Series oscilloscopes. All specifications are guaranteed unless noted as “typical.” Typical specifications are provided for your convenience but are not guaranteed. Specifications that are marked with the n symbol are checked in Performance Verification.
All specifications apply to all TDS3000B models unless noted otherwise.
To meet specifications, two conditions must first be met:
HThe oscilloscope must have been operating continuously for twenty minutes within the operating temperature range specified.
HYou must perform the Compensate Signal Path operation described on page 2-22 prior to evaluating specifications. If the operating temperature changes by more than 10 °C, you must perform the Compensate Signal Path operation again.

2To ensure compliance to the standards listed above, attach only high quality shielded cables to this instrument. High quality shielded cables typically are braid and foil types that have low impedance connections to shielded connectors at both ends.
3The 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 8 major divisions peak-to-peak. Ambient conducted fields may induce triggering when the trigger threshold is offset less than 4 major divisions from ground reference.
4The 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
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.
