<blockquote>
DESCRIPTION
This manual describes MOD 709V as it applies to the
TEKTRONIX 5110 Single Beam Oscilloscope.  MOD 709V
adds a new circuit board for X-Y operation using Right
Vertical versus Left Vertical. Using a TEKTRONIX 5B10N
MOD 709V Time Base plug-in unit, the SECONDS/DIV or
VOLTS/DIV switch is turned to the L versus R position
actuating a switching relay mounted in the mainframe. This
bypasses the normal sweep function of the 5B10N, allowing
for a Left Vertical versus Right Vertical X-Y display. The
display unit portion of the 5110 is supplied with an
illuminated graticule with a special implosion shield, and an
AC coupled EXT INTENSITY INPUT via a yellow binding post
at the front panel.
BANDWIDTH
Maximum horizontal deflection bandwidth
(using a 5A15N or 5A18N amplifier) is reduced by
approximately 300 kHz by the added wiring. Bandwidth (-3 dB)
for X-axis deflection from either the center or right compartment
is 1.7 MHz minimum. The Y-axis specification is unchanged.
CALIBRATION
Check the interconnecting wiring to the added  X-Y circuit board,
then calibrate MOD 709V according to the procedure in the 5110
Instruction Manual.
5A19N MOD 709V
This manual insert describes the features of MOD 709V as installed in the 5A19N
Differential Amplifier. The Signal Input connector has been changed to a blue
binding post for the Minus Input. The Variable VOLTS/DIV control labeled CAL
has been removed. A +15 Volts offset, regardless of the VOLTS/DIV control
setting has been added
5B10N MOD 709V


This manual insert describes the features of MOD 709V as installed in the 5B10N
Time Base Amplifier. It removes the VAR control, changes the BNC EXT INPUT
connector to a green binding post and provides a switching mode for
Left Vertical vs Right Vertical, The last ccw position of the SECONDS/DIV or
VOLTS/DIV (EXT) switch is now labeled L vs H.
</blockquote>


Note the rotary switch position described in the manual insert differs from the separate switch apparent in the examples.
