Timebase system

✓Timebase factory tolerance Frequency tolerance at factory calibration is ±12 ppb (parts per billion).

At Calibration, 25 °C ambient, over any ≥1 ms interval.

Timebase temperature stability ±20 PPB across the full operating range of 0 °C to 50 °C, after a sufficient soak time at the

temperature. The instrument needs to soak at a fixed temperature for an extended period of time to insure

the time-base frequency is stable. The following is a worst case estimation for the frequency error versus the amount of time the instrument has been soaking at a temperature.Max error (in ppb) = ±10^[log[100/soak time(in hours)]]

For example, a 1 hour soak will have a max frequency error of ±100 ppb, but a 10 hour soak will have a max frequency error of 10 ppb.

±300 PPB/Year, and will not exceed ±2 PPM over 10 years without calibration. Calibration will reduce this frequency error to under ±12 PPB Frequency tolerance change at 25 °C over a periods of 1 year and 10 years.

Horizontal scale range 40 ps/div to 1000 s/div

The minimum horizontal scale is determined by the record length by dividing the record length by 10 (because there are 10 divisions on-screen) and then dividing by the maximum sample rate (2.5 TS/s).

40 ps/div can only be achieved with a 2.5 TS/s sample rate (maximum) and a 1000 point record length (minimum).The table below shows minimum horizontal scales for a collection of record lengths.

1000 s/div is the maximum horizontal scale which limits the acquisition length to 10000 s (2 hours, 46 minutes and 40 seconds).

Below a record length of 62.5 kS, the horizontal scale is further limited. The maximum horizontal scale can be calculated by dividing the record length by 10 (because there are 10 division on-screen) and then dividing by the minimum sample rate (6.25 S/s).The table below shows maximum horizontal scales for a collection of record length.

This limit is checked by SPC at very low frequency (nearly DC).

This limit does not include frequency dependent effects, edge type trigger sensitivity not DC coupled, or trigger position error.

Set the trigger level to the desired value. Using an adjustable DC source, inject a voltage into the instrument. Adjust the voltage downward (if checking negative slope) or upward (if checking positive slope) until the scope triggers. The difference between the trigger level setting and the voltage that actually caused the trigger is the trigger level accuracy.
