Setting up the test environment

Compensate the signal path

Use the following procedure to compensate the internal signal acquisition path. Perform this procedure if the ambient temperature has changed more than 5 °C (9 °F) since you performed the last signal path compensation. Perform the signal path compensation once a week. Failure to do so may result in the instrument not meeting warranted performance levels.

1. Power on and wait for the instrument to complete its warm up period before continuing with this procedure.

2. Disconnect any probes you have connected to the input channels.

3. Set the instrument to Menu mode.

4. Select Instrument Calibration from the Utilities menu.

5. Note any instructions that appear in the resulting control window

6. Click Run SPC to begin the procedure. The procedure may take several minutes to complete.

7. Verify that the Status changes to Compensated after the procedure is complete. If the Calibration Status field indicates anything other

than Compensated, see Signal Path Compensation Status for information on the readout and recommended action.

Note: When making measurements at vertical scale settings less than or equal to 5 mV compensation at least once a week. Failure to do so may result in the instrument not meeting warranted performance levels at those volts/div settings.

, you should perform the signal path

Deskew

If skew is present between positive and negative channels, then the channels need to be deskewed before being used for waveform measurements.

Apply the appropriate input attenuator such that the signal on the screen for each channel can be adjusted (using the oscilloscope's V

ertical > Scale settings) to less than 10 division Pk-Pk but greater than 8 division Pk-Pk.

Use maximum instrument bandwidth so narrow noise peaks that might reach out-of-range are visible in their full amplitude, rather than limited by the post-digitizer bandwidth processing. Set the record length to 50 MSa or longer; Measure both channel 1 and channel 2 with a Measure > Amplitude > Peak - Peak to monitor that the trace is without clopping, that is the measurements don't display a warning indicating over-driven input.

TekExpress 400G-TXE provides support for channel deskew and attenuation using the following method:

1. Determine what the skew is for each channel.

Please use method recommended by Tektronix. DPO70k SX oscilloscope to find the skew, for example, minimum common mode. Tektronix recommends using channel 1 as a reference with 0 skew, and entering a measured skew value in channel 2.

2. From the TekScope menu, select Vertical > Deskew.

3. In the Deskew/Attenuation window, click the channel 1, and set the skew to 0. Then select channel 2 button for the first channel to be

deskewed.

4. Click in the Ch(x) Deskew Time entry field and enter the skew. The skew can be +ve or –ve.

5. Click the channel button for the next channel and repeat step 4.

6. After entering the skew for all the channels that require it, from the Options menu in TekExpress 400G-TXE, select Deskew.
