Ch 2 Invert Switch - Tektronix 2212 User Manual

Vertical
CHOP -
In the CHOP mode the display switches be-
tween the CH 1 and CH 2 vertical input signals during
the sweep. The chopped switching rate (CHOP fre-
quency) is approximately 500kHz.
In Store mode, both signals are acquired simultaneously.
There is no functional difference between ALT and
CHOP except when VERT MODE triggering source is
selected.
X-Y - In the X-Y mode, the CHl OR X input signal pro-
vides horizontal deflection and the CH 2 OR Y input
signal provides vertical deflection on the crt screen. In
the crt readout "X-Y" is displayed.
You can select the X-Y mode in the Non-Store as well as
in the Store mode.
When using the cursors,
ii
Vl becomes
ii
VX and
ii
V2
becomes
ii
VY.
In X-Y Store mode, the full acquisition length is equal
to the SEC/DIV switch setting times 10.24 (SEC/DIV X
10.24).
In X-Y Store mode, with the SEC/DIV switch in EXT
CLK position, the full acquisition length is equal to 4096
divided by the Clock Frequency of the EXT CLK input
signal (4096 : Clock Frequency).
CH 2
-In CH 2 mode, only the CH 2 input signal is
selected for display.

CH 2 INVERT Switch
5-10
The CH 2 INVERT switch inverts the CH 2 display when in
the invert position. An invert symbol ("
J ")
is displayed in
the crt readout when CH 2 is inverted.
With CH 2 inverted, the oscilloscope may be operated as a
differential amplifier in the ADD mode.
