Tektronix 608 monitor Instruction Manual page 130

Instrument Options—608
C. HORIZONTAL (X) AMPLIFIER—OPTION 22
Additional Equipment Required:
1. Dual-input coupler
2. Function generator (for instruments also equipped with Option 21)
CO. ADJUST HORIZONTAL ATTENUATION
COMPENSATION (C310 and C410)
NOTE
For a complete procedure, perform this step
prior to step C1 (Check/Adjust Horizontal
Compensation) of Section 6, Performance
Check and Adjustment.
SETUP CONDITIONS
NOTE
For a partial procedure, first perform the
Horizontal Preliminary Control Settings
given in section 6, then proceed with the
following instructions.

c. EXAMINE—The display for optimum square corner.
OPTION 22—PAGE 4
Perform the remaining parts of this step
only if your instrument is equipped with
both Option 21 and Option 22.
e. Disconnect the square-wave generator from the +X
INPUT and connect it to the -X INPUT. Place the
grounding cap on the +X INPUT.
f. EXAMINE—The display for optimum square corner.
g. ADJUST—C410 (-X Atten Comp) for optimum
square corner using a low-capacitance screwdriver.
C3. CHECK HORIZONTAL COMMON-MODE
REJECTION
NOTE
For a complete procedure of those
instruments equipped with both Option 21
and Option 22, perform this step following }
step C2 (Check/Adjust X GAIN) of Section
6, Performance Check and Adjustment. X
GAIN must be set for 8 divisions of
deflection per volt of input signal when
checking Horizontal Common-Mode
Rejection.
