PASSIVE PROBE (TEXAS-xx/I series)

TEXAS20/I, TEXAS40/I, TEXAS60/I,TEXAS100/I
  • Texas's latest design of Passive Oscilloscope Probes feature a one piece (monolithic) design for robust probe life
  • Probe bandwidth ratings are specified as system bandwidth. System bandwidth includes both probe and oscilloscope together as a system. The result is a probe frequency response that essentially can be considered transparent.
  • Full set a accessories are included with each probe.
  • All probes meet IEC1010-2-031,600Vpp, CATII

Low Frequency Trimmer Adjustment:

Low frequency response can be matched to the oscilloscope by adjusting the compensation trimmer on the head of probe.
  1. Connect the probe to the oscilloscope and to a 1KHz. Square wave source, the rise time should not exceed 10 microseconds (most oscilloscopes provide a probe compensation output). For X1/X10 probes, switch to the X10 position.
  2. Set the oscilloscope to display two to three cycles and two to six vertical divisions.
  3. Carefully adjust the trimmer tool to obtain the flattest tops to the square waves displayed on the oscilloscope, see illustrations

High Frequency Trimmer Adjustment:

(Model TEXAS150/I, TEXAS200/I and TEXAS250/I, TEXAS150/II, TEXAS200/II, TEXAS250/II)
The high frequency compensation has been pre-adjusted at the factory, however if adjustment is required, use the following procedure.
  1. The high frequency compensation box cover located near the connector, Use the BNC adapter, connected the probe to a square wave generator operating between 10 to 100KHz terminated into 50ohms. The square wave generator rise time should be approximately.125ns. Adjust each control until the leading edge of the waveform is as flat, square and horizontal as possible
  2. (see high frequency illustrations). The best take it to careerman for assistance.
  3. Readjust the low frequency compensation if necessary.
