Tektronix 556 Dual Beam Oscilloscope Testing: Vertical Bandwidth

I have been doing some basic testing of my Tektronix 556 Dual Beam Oscilloscope, and I have documented some parts of this process.  I have also captured images of the traces, which I will share here.

Test Setup: Tektronix 556, 1A2 plug-in, Timebase A, Tektronix SG 503 Generator, and Tektronix TG 501 Time Mark Generator

I found the -3db vertical bandwidth of the 1a2/556 to be 65 Mhz, which is to be expected for the 50 Mhz rated 1A2.

 

TM 500 Module with Plug ins

50 kHz Reference Signal 6v peak to peak

5 MHz Sine Wave 6v peak to peak

20 MHz Sine Wave 6v peak to peak

40 MHz Sine Wave 4.8v peak to peak

50 MHz Sine Wave 4.3v peak to peak

65 MHz Sine Wave 4.2v peak to peak

I will continue this testing by investigating the absolute maximum trigger … Read More »
