Scope range adds capacitive touch, zone triggering

January 12, 2015 // By Graham Prophet
Keysight Technologies’ InfiniiVision 3000T X-Series digital-storage and mixed signal oscilloscopes come with what Keysight terms intuitive graphical triggering capability.

The series adds capacitive touch screens and zone triggering, which Keysight says will help engineers overcome usability and triggering challenges and improve problem-solving. Intuitive graphical triggers, previously unavailable in mainstream oscilloscopes, help engineers debug and characterise their devices faster and more easily. With graphical triggers, engineers can use a finger to draw a box around a signal of interest on the instrument display to create a trigger.

These oscilloscopes have upgradable bandwidths from 100 MHz to 1.0 GHz in addition to the touch screen interface and graphical zone triggering capability. An uncompromised update rate of one million waveforms per second gives engineers visibility into subtle signal details. The series comes with six-instruments-in-one integration, including oscilloscope functionality, digital channels (MSO), protocol analysis capability, a digital voltmeter, a WaveGen function/arbitrary waveform generator, and an 8-digit hardware counter/totaliser. The 3000T X-Series delivers correlated frequency and time domain measurements using the gated FFT function for the first time in this class, to address emerging measurement challenges.

The 3000T X-Series was designed specifically for operation with a capacitive touch screen, which allows engineers to select targets naturally and quickly. To further improve productivity, the interface includes an alphanumeric touchpad that replaces tedious knob-based operation and touch-based interaction that enables greater flexibility in displaying measurement information. Keysight claims that with the series' high-speed waveform update rate, even with the digital channel, protocol decode, measurements and math functions turned on, and with the simplicity of zone touch triggering, engineers have the highest probability of discovering anomalies of interest.

The 3000T X-Series supports a wide range of popular and emerging serial bus applications: MIL-STD 1553 and ARINC 429, I2S, CAN/CAN-FD/CAN-Symbolic, LIN, SENT, FlexRay, RS232/422/485/UART and I2C/SPI. The new gated FFT function allows engineers to correlate time and frequency domain phenomenon on a single screen. Power analysis, video analysis and hardware-based mask test option makes the 3000T X-Series a comprehensive mainstream oscilloscope.
