Page 5: Introduction
The MS-250 is ideally suited for embedded controller testing where there is a proliferation of analog signals coincident with digital signals. You can easily debug signals using standard oscilloscope tools such as cursors, measurement parameters, and zooming. - Page 6 While in SINGLE, NORMAL, or AUTO trigger mode, the MS-250 repeatedly samples each digital channel’s voltage level. If the voltage is above the threshold, the MS-250 stores a 1 in internal memory; if it is below threshold, a 0 is stored.

Page 11: Connecting The Mixed Signal Device
Operator's Manual Connecting the Mixed Signal Device Connecting the Unit To connect the Mixed Signal accessory to your oscilloscope: 1. Connect the Bus Cable to the LBUS connector on the oscilloscope. Be sure the head is turned so that the positioning wedge fits into the groove at the top of the connector. - Page 12 MS-250 Mixed Signal Oscilloscope Option 3. Connect the other end of the Bus Cable to the MS-250. Again, be sure to align the wedge and the groove. Fasten the thumb screws. 4. Connect the other end of the USB 2.0 Cable to the MS-250.
- Page 13 Operator's Manual 5. Connect the Digital Leadset to the Digital Inputs D0 – D17 connector on the opposite end of the MS-250 and fasten the thumb screws. NOTE: Each digital line has a ground connection for optimal performance. Two additional ground leads common to the whole leadset are also available.

The standard terminations on the digital leadset can be pushed directly onto 25-mil pins. MicroGrippers or NanoGrippers may also be used to probe the test circuit’s pins. Teledyne LeCroy provides a selection of small, medium, and large grippers for various pitch sizes. A more complete selection of adapter probes is available for most chips from Emulation Technology Inc.,... -
Page 15: Digital Logic Setup
Operator's Manual Digital Logic Setup Threshold Level The threshold level determines how the input signal is interpreted. Input voltages below the threshold are converted to 0/Low, while input voltages above it are converted to 1/High. Figure 2. Threshold level determines high-low of digital waveform. To set the logic threshold: 1. - Page 16 MS-250 Mixed Signal Oscilloscope Option Minimum Voltage (Hysteresis) You can define the minimum high and low voltage levels using the Hysteresis controls. Hysteresis can help prevent false determinations on variable signals. Hysteresis can be set up to 1.4 V above or below threshold.

Page 17: Digital Group Setup
Operator's Manual Digital Group Setup This procedure organizes the digital lines into groups, which correspond to buses. The lines within a single group can be displayed individually or collapsed into a Bus trace. You can set up a total of two, distinct groups: Digital1 and Digital2. Each group is designated by its own Digital setup dialog. -
Page 18: Displaying Digital Traces
MS-250 Mixed Signal Oscilloscope Option Displaying Digital Traces The Trace On checkbox is selected by default, so if you are connected to a live input, you should see digital traces appear as you add lines to the group. To turn off the trace display, clear Trace On. -
