Section 1: Getting Started Model 4200-SCS User’s Manual
SCP2 (Oscilloscope)
Keithley Instruments offers two scope cards: 4200-SCP2HR and 4200-SCP2. However, only one
scope card at a time can be used in the 4200-SCS system.
The scope card is a modular, dual-channel, high-speed digital storage oscilloscope (DSO). It uses
a high-speed memory digitizer (DC to 700 MHz) and an embedded digital signal processor (DSP).
The scope card has two input channels to capture and analyze a variety of time-varying signals.
KScope, a soft front-panel software used to view pulse waveforms, is included with the
4200-SCP2HR and 4200-SCP2 (see the “How to Generate Basic Pulses” in Section 5 for details).
KScope provides full control of the DSO and allows export of waveform data that is compatible
with Microsoft
®
Excel
®
. The plug-and-play drivers can be used in most application programming
environments (for example, National Instruments LabVIEW™, Microsoft® Visual Basic
®, and
Microsoft
® Visual C++®).
The primary differences between the two scope cards are ADC resolution and sample rate:
• 4200-SCP2HR: 16-bit resolution, single-channel sampling rate of 400-million samples per
second (400 MS / s)
• 4200-SCP2: 8-bit resolution, single-channel sampling rate of 2.5 billion samples per second
(2.5 GS / s)
Basic pulse characteristics of the two scope cards are listed in Table 1-2. See the supplied ZTEC
User’s Manual for complete specifications of the scope card.

NOTE Refer to the Reference Manual, Pulse source-measure connections, page 11-38 for
details about scope card connectors and connections to DUT.
