Performance verification procedures
NOTE.
If your instrument firmware version is v1.02, it should be updated before performing the performance verification procedures.
Download the latest firmware from www.tek.com/software.
The following three conditions must be met prior to performing these procedures:
■
The instrument must have been operating continuously for twenty (20) minutes in an environment that meets the operating
range specifications for temperature and humidity.
■
You must perform a signal path compensation (SPC) before beginning these procedures. If the operating temperature
changes by more than 10 °C (18 °F), you must perform the signal path compensation again.
■
You must connect the instrument and the test equipment to the same AC power circuit. Connect the instrument and test
instruments into a common power strip if you are unsure of the AC power circuit distribution. Connecting the instrument 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.
TBS2000 Series Specification and Performance Verification 13
Performance verification
WARNING. Some procedures use hazardous voltages. To prevent electrical shock, always set voltage source outputs to 0 V
before making or changing any interconnections.
