This chapter provides an overview of the 53210A Status System. Refer to the
STATus subsystem and the IEEE-488 commands within the Programmer’s

Questionable Data Register Group
The counter’s Questionable Data Register Group monitors the following
conditions and events within the counter:
– input voltage overload
– frequency measurement hardware time out
– calibration data
– time base error
– lower-limit exceeded
– upper limit exceeded
– reading memory overflow
Condition Register
The Condition Register within the Questionable Data Register Group monitors
current conditions that may impact the integrity of the counter measurements.
The Condition Register is read with the command:
STATus:QUEStionable:CONDition?
Reading the register does not clear the bit(s) in the register. The bit is cleared
when the condition is removed.
Event Register
The Event Register within the Questionable Data Register Group also monitors
conditions that may impact the integrity of the counter measurements.
