Probe suits vehicle testing buses
The PBH1000 is robust enough for use in the in-vehicle test environment and will withstand maximum voltages of +/-100V (transient) and +/-35V.
The Yokogawa PBDH1000 is a high-frequency differential probe designed to meet the challenges involved in the development and testing of in-vehicle buses such as CAN and FlexRay The new probe is intended for use with the Yokogawa DL9000 series of oscilloscopes or the SB5000 range of serial bus analysers

Versatile tester for IEEE-1394 bus
The new FireWorks 1394 VK9000 from Yokogawa Martron is designed to provide engineers with a powerful 'out of the box' solution for testing systems based on the IEEE-1394 bus.
It has a frequency bandwidth of DC to 1GHz (-3dB or more), an attenuation ratio of 50:1 and a DC accuracy of within +/-2%.
The PBH1000 overcomes the limitations encountered when using standard oscilloscope probes for high-frequency serial bus testing.
Standard oscillipscope probes typically provide limited voltage range, susceptibility to transient surge damage and excessive input capacitance or low impedance.
In particular, signals measured using standard probes can appear lower than expected due to loading effects of the probe.
The PBH1000 is robust enough for use in the in-vehicle test environment and will withstand maximum voltages of +/-100V (transient) and +/-35V.
Input impedance is approximately 1Mohm and 1.1pF to ground and differential input impedance is approximately 2Mohm and 0.6pF.
Probe power is supplied via the oscilloscope input connector.
Typical applications include observing waveforms on in-vehicle CAN or FlexRay bus systems, checking the noise on high-speed devices for bus power supplies and evaluating the digital circuit within bus systems.
