APPENDIXA:SPECIFICATIONS
OSCILLOSCOPE
Unless otherwise indicated, all technical specifications are applicable to the 10X probe
attenuation switch setting. The oscilloscope should meet the following requirements in
order to meet the published specifications.
■ The instrument should be allowed to run continuously for more than 30 minutes under
the specified operating temperature
■ If the operating temperature is exceeded by more than 5 degrees Celsius, an “Auto-
calibration” must be performed (system function menu)
