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.

Record length range

Applies to analog and digital channels. All acquisition modes are 1 G maximum record length, down to 1 k minimum record length, adjustable in 1 sample increments.

Standard: 62.5 Mpoints

Option 6-RL-1: 125 Mpoints

Option 6-RL-2: 250 Mpoints

Option 6-RL-3: 500 Mpoints

Option 6-RL-4: 1 Gpoints

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).

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.

Maximum Number of Frames in FastFrame, typical
For system memory depths up to 250 M, and for record length ≥ 1,000 points, maximum number of frames = system memory depth / record length setting.
For system memory depths of 500 M, and when only channels capable of a maximum sample rate of ≥ 25 GS/s are used, maximum number of frames = system memory depth / record length setting.
For system memory depths of 500 M, and when any channels capable of a maximum sample rate of 12.5 GS/s are used, maximum number of frames is ≥ 250,000.

User must select either 10 MHz external (±1 kppm), 10 MHz external (±1ppm), or the internal reference (default) from the UI.
Frequency Variation Tolerance
Low Phase Noise Mode: 9.99999 MHz to 10.00001 MHz (±1 ppm)
Tracking Mode: 9.99 MHz to 10.01 MHz (± 1000ppm)*
Loop Bandwidth of external tracking mode is a function of the PLL loop maximum slew rate capability, and is not linear. The modulation deviation frequency (±Hz) is dependent upon the maximum modulation rate (Hz). For example, a deviation of ±50 Hz or less can tolerate any modulation rate. A deviation of the maximum amount specified for this mode (±10 kHz or 1 kppm) will tolerate up to 80 Hz of modulation rate. A deviation of ±500Hz will tolerate up to about 1240 Hz of modulation rate. This is based on a measured instrument response to the reference clock being modulated. Example measurement is in the below table.

You might need additional cables and adapters, depending on the actual test equipment you use.

These procedures cover all MSO64B, MSO66B, and MSO68B models. Disregard checks that do not apply to the specific model you are testing.

Print the test record on the following pages and use it to record the performance test results for your oscilloscope.

Note:Completion of the performance verification procedure does not update the stored time and date of the latest successful adjustment. The date and time are updated only when the adjustment procedures in the service manual are successfully completed.

The performance verification procedures verify the performance of your instrument. They do not adjust your instrument. If your instrument fails any of the performance verification tests, you should return the instrument to Tektronix for adjustment or repair.
