GGB Picoprobe Model 34A Active Probe (DC to 3 GHz) High Impedance Probe
The PICOPROBE® MODEL 34A is designed to connect to the mounted onto our EB-050 and EB-005 micropositioners to help prove high frequency circuit designs. The Model 34A achieves its 3GHz bandwidth using just one probe point without sacrificing performance.
An assortment of user replaceable probe tips are available for a variety of probing needs. The Model 34A is powered by our standard PS-2 Picoprobe® power supply.
The PICOPROBE® MODEL 34A is engineered to meet the stringent demands of advanced high frequency circuit designers. This high impedance probe combines full DC capability, rise/fall times of 120 ps, and a nominal loading input impedance of 10 megohm shunted by 0.1 pf. Signal attenuation is 20:1 with a 50 ohm oscilloscope input. Like our other active probes, the Model 34A achieves its bandwidth using just one probe point, which greatly simplifies internal node testing without sacrificing performance.
Note needs PS-2 Power Supply for 12C, 18C, 19C, 28, 29 and 34A (operates two probes) Part No. 66944
