If TekExpress is running on an instrument having a video resolution lower than 800x600 (for example, sampling oscilloscope), it is recommended
to connect a secondary monitor and this must be enabled before launching the application.

If TekExpress is installed on a Tektronix oscilloscope, the virtual GPIB port will be used by TekExpress for communicating with oscilloscope
applications. If external GPIB communication devices like USB-GPIB-HS or equivalent are used for instrument connectivity, ensure that the Talker
utility is enabled in the DPO/DSA oscilloscope's GPIB menu. For ease of use, connect to an external (secondary) monitor.

For temperature chamber testing, a filter file with S4 parameters is used to compensate the factors
introduced due to length of the probe cable when testing the DUT in temperature chamber. You will
need one or two filter files based on the selected clock probing. If you select Single-ended probing,
you mu
st specify only one filter file (Filter File 1). The application ignores the Filter File 2 even if
you provide it. If you select Differential probing, then you must specify both the filter files (Filter

Temperature Chamber Testing
The TekExpress D-PHY offers the temperature chamber testing which is done at system level when the
device is put in the oven and the connection points from the DUT are extended to the probe using a wire.
This wire is 60” (5 ft) long and the signal must be de-embedded for t he measurement. Filter files are
needed to offset the cable effects that are introduced in temperature chamber testing.
The setup shown below is expected to be done by the user. The DUT is ideally placed in an environment in
which t he temperature can be externally controlled, which we call the Temperature Oven. The DUT is
then connected to the setup using the above-mentioned long cables that come from within the oven to

1. Connect a GPIB cable between the oscilloscope and the RF switch.
2. Connect the input channels of the oscilloscope to the outputs of the Probing board.
3. Connect the inputs of the Probing board to the outputs of the RF switch.
4. Connect the Dp signals form each lane of the DUT to the inputs of channel 1 of the RF switch.
5. Connect the Dn signals from each lane of the DUT to the corresponding inputs of channel 2 of the
RF switch.
6. Connect the Cp signal to the input of channel 3 of the RF switch. The clock lane is connected through
the RF switch to ensure that there is no skew between the data and clock signals.
