Measured peak-to-peak. Tested with Agilent 53132A frequency counter. Due to the low operating frequency, the gate time
must be
≥100ms
to ensure an accurate frequency measurement.
Measured peak-to-peak. Inclusive of initial tolerance at +25°C, and variations over operating temperature, rated power
supply voltage and load.
