Cal Test's mini passive voltage probes work at 500 MHz
-- Test & Measurement World, 2/27/2008 7:11:00 AM
Two 10X passive voltage probes from Cal Test Electronics feature a slim 3.5-mm body, 500-MHz bandwidth, and compatibility with Tektronix TDS3000B, DPO4000, and DPO7000 series oscilloscopes. The CT3290RA and CT3290RA-PRO also work with the same accessories as the Tektronix P6139A passive voltage probe. You can use the Cal Test probes as cost-effective replacement probes for a wide variety of industrial, medical, control, electronic, and electrical applications.
Both oscilloscope probes have a 300-V CAT II IEC safety rating and provide a rise time of 0.7 ns, input impedance of 10 Mohm, input capacitance of 8 pF, and output impedance of 1 Mohm. In addition, the probes include a readout actuator (sense pin) that makes them compatible with oscilloscopes that automatically detect and display the probe’s attenuation factor.
The CT3290RA comes with an attenuator cover, slip-on ground lead with alligator clip, sprung hook, ground collar, low-impedance tip, trimmer tool, slip-on ground lead with 0.6-mm socket, IC clip, and probe identifier rings. The CT3290RA-PRO is a deluxe version of the CT3290RA and adds the following accessories: cover shell with slip-on ground lead, cover shell without slip-on ground lead, tip insulator, IC tip insulator, BNC adapter, IC lead combs, twin-lead adapter and two IC clips, and probe tip grounds.
The CT3290RA oscilloscope probe costs $230. The CT3290RA-PRO oscilloscope probe costs $290.
