Tektronix vertical signal output

[mike zias]

I have a 7623A scope and trying to use the vertical signal output on the back panel in the fashion of using the old 1A1 preamp.
I find the output is attenuated - dividing the input on the vertical plug in by 2.  Is that normal?  I have seen a spec for another scope as 0.5 v per
division with 1 meg load..  I don't understand that spec.What division are they referencing?  How does that account for the 2:1 division?

Per displayed division on the CRT.

Where the vertical signal out is picked off the voltage swing has been normalised to suit the deflection inputs sensitivity of the CRT amplifier.  So the signal levels here are a fixed range relating the the full scale CRT deflection range

The vertical output should be 25 millivolts into division into 50 ohms and 0.5 volts per division into 1 megohm.  The divisions are vertical divisions shown on the CRT graticule.
