  • Page 33: Operating Basics

    Operating Basics Input Connections The top panel of the instrument has four safety BNC jack signal inputs. The color at the base of each BNC input corresponds to the color of the related channel button on the front panel. Isolated input architecture allows independent floating measurements with each input.

  • Page 34: About Floating Measurements

    Operating Basics About Floating Measurements You can use the independently floating isolated inputs to measure signals that are independently floating from each other. The instrument has independently floating isolated inputs. Each input section (1, 2, 3, and 4) has its own signal input and its own reference input.

  • Page 35: Figure 8: Common-Reference Input Architecture

    Operating Basics Many handheld oscilloscope products have the architecture shown below, which shares a common reference for the oscilloscope channels. (See Figure 8.) With this architecture, all input signals must have the same voltage reference when you take any multi-channel measurements. Figure 8: Common-reference input architecture Most bench-top oscilloscopes share the architecture shown above, but without the insulated case.

  • Page 36: Connect Probes And Leads

    WARNING. To avoid electric shock, do not use probes that require a ground connection, such as the Tektronix P5200 High Voltage Differential Probe, with the THS3000 Series Oscilloscopes. The P5200 High Voltage Differential Probe requires an instrument with grounded inputs and the TH3000 Series Oscilloscopes have floating inputs (isolated inputs).

  • Page 37: Figure 9: Parasitic Capacitance Between Probes, Instrument, And Environment

    Operating Basics Attach the Reference If you are using all four of the instrument channels, you must attach the probe reference lead for each channel directly to your circuit. These attachments Leads Correctly are required because the channels are electrically isolated; they do not share a common chassis connection.

  • Page 38: Figure 10: Parasitic Capacitance Between Analog And Digital Reference

    Operating Basics Parasitic capacitance between analog and digital reference. Parasitic capacitance can occur between the input references mutually. For example, between an analog and digital reference. For this reason, you should connect the references to a system ground or another stable voltage. If the reference of an input is connected to a high speed and/or high voltage signal, you should be aware of parasitic capacitance.

  • Page 39: Figure 12: Wrong Connection Of Reference Leads

    Operating Basics This is a the wrong way to connect reference leads. Noise that is picked up by reference lead 4 can be transmitted by parasitic capacitance to the analog input amplifier.
