The already excellent price/performance ratio of the R 1029 has been improved even further. Both vertical Amplifier now incorporate variable gain controls and maximum input sensitivity is 2mV/cm over the full bandwidth of the Oscilloscope Another new feature permits display of the sum and difference of two signals. Triggering facilities have also been expanded. In addition to line and TV triggering, HF and DC triggering are now possible. The R1029B will trigger stably with a 5mm display height up to at least 40 MHz. Using the manual level control, even relatively complex signals can be stably triggered. An 8x10cm internal graticule permits parallax-free viewing over a wide angle. The effect of the earth's magnetic field upon horizontal trace position can be compensated for, externally, with a trace rotation control. The R1029B has a built-in component tester, which is especially useful in maintenance and servicing work. Among other applications, this device enables rapid, in-circuit testing of semiconductors. Test voltage and current are rated so that normal semiconductors or other components cannot be damaged. Test results are displayed on the scope screen. The R1029 B was designed for general purpose applications in industry and service. Its many operating modes, front panel layout, and ease of operation also make it an ideal Oscilloscope for use in training engineers and technicians.
