The 11A34 is compatible with Level 1 and
Level 2 TEKPROBEs.*
*DC drift can be calibrated out by invoking a calibration (Enhanced Accuracy) at any specific
"operating temperature.
*Display ratio =
Amplitude (div) x V/div (driven channel)
Error amplitude (div) x V/div (undriven channel)
*TEKPROBE is Tektronix' name for the interface used with probes designed for the 11000-series
of oscilloscopes and plug-in units. TEKPROBEs have output connectors with one or more spring
loaded coding pins. Two categories of TEKPROBEs are:
Level 1
A level 1 probe, which uses analog encoding to indicate the probe's scale factor to the
plug-in unit.
Level 2
A level 2 probe, which uses an EEPROM to store data about the probe's transfer units,
scale factor, and output voltage scale factor. Such data are serially encoded, then stored in
the EEPROM. The probe data is intended to be read once at instrument power-up or when
the probe is first connected to a plug-in unit (that is, at probe power-up).
