Thank´s for your help, I already recived these manual from you
;
Thank you for your manual It has the basic things to and i use the Oszi for Longer Time.

Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.

Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.
Figure 45. Settling time characteristic for resistance measurements assuming <200pF shunt capacitance in the circuit tested. For small values of resistance, there is no real advantage to setting the delay to less than the default values. Resistance above 100 kW require longer settling times to reach final values: hence settling delay times for these values may save measurement time at the expense of measurement accuracy.
Another feature of the 3458A is OffsetCompensated Ohms. Very much like auto zero in concept, offset-compensated Ohms makes a measurement of the input resistance without the current applied to measure any thermally generated DCV offsets. As shown in Figure 46, the current is applied, the offset voltage is subtracted from the measurement of the unknown resistance and the result is presented to the display. Like auto zero, it takes two measurements to make a final determination of the unknown resistance. In reality, offsets like this are only encountered in lower values of resistance. The 3458A offers a 10 mA current source that will, at least, mask the effect of the thermally generated offset. Hence, in many cases Offset-Compensated Ohms may not be needed for lower resistance measurements.
Figure 46. Offset compensated ohms removes the effect of small series voltage sources such as thermocouple effects in the circuit. By measuring the voltage across the unknown resistance, Ve, with the current source off and then measuring the voltage across the unknown resistance with the current source on, the effect of Ve on the measurement is eliminated.
