4 Channel PC Oscilloscope, 200 MHz Bandwidth

Product Overview:

The CS448 is an individually isolated channel high CMRR oscilloscope with four channels which are isolated from each other with a fiber optic cable. Indeed, the channel to channel Isolation offers a minimum clearance of 6.6 mm which minimizes the effects of system noise. This translates to a higher signal integrity and high sensitivity that manifests itself through an isolation capacitance of < 14pf, a spectral noise floor of -100 dBV, a channel to channel Skew of < 144ps, a CM leakage to other channels set at <-125dBc, and a sample clock jitter of 300 fs rms. Moreover, it is designed to measure all the signals in an operating full or three phase power electronic switching bridge. Examples of these measurements include, gate drives to measure voltage and charge, the power switch to measure loss and parasitic stress, the output to measure power and spectrum for EMC compliance, and the control system for Gain/Phase and stability. The CS448 also includes an isolated signal generator for stimulus, and eight digital inputs to measure control signals. Consequently, this implies that the two CS448's can be slaved to make an 8-channel oscilloscope with coherent sampling. Review of Key specifications The Digital Port on the CS448 is based on a programmable logic IC and can be used for generating complex state-based sequences or reacting to a complex set of inputs. Accordingly, the port includes triggering capability with trigger in/out and control. As for the Link Port, it is used for controlling Cleverscope accessory devices such as the CS1070 1A 50 MHz power amplifier, and the CS1110 VCE Sat Probe. In fact, it also includes RS232, SPI and I2 C ports for controlling user equipment. With an output frequency range of DC - 65 MHz, its output ensures maximum flatness and maximum smoothness for both unfiltered and filtered for frequency response analysis. Accordingly, the real time sample filtering improves dynamic range and faster peak capture that can run peak capture closer to real time.
