Re: 475 instead of 475A?
Hi,toggle quoted messageShow quoted text
If you are really interested in looking at low level signals you may want to consider the 7603 mainframe and a 7A22 vertical plugin.
The 7A22 has a sensitivity of 10uV /div and has built in high and low pass filters. The maximum bandwidth is limited to 1MHz. The differential input will allow you to look at ballanced as well as unbalanced signals. It is well suited for audio work.
A 7A26 vertical amplifier can be added for two channels of vertical with 100MHz of bandwidth.
A 7B53 dual timebase completes the configuration.
The scope is bigger and heavier than the 475 but the performance is increased.
The 7000 series is available quite cheaply.
I am not sure if some of the 475s had nuvisters, whereas the 475As are all solid state. I am sure other members of the group can comment on this.
