OPERATION
r-CAUTION:
For DUAL operation be sure to set the TRIG MODE control to
AUTO to allow sweep of both A and B to be performed.
When A and B Sweeps are to be used alternately, the CS-
2100A must be set up to provide both sweeps.
[6] X-Y OPERATION
Phase difference measurements may be made with the CS-
2100A by use of the X-Y display mode.
Procedure:
Set the HORIZONTAL DISPLAY control to the X-Y mode. In
this mode the CH
1
input becomes the Y-axis input and the CH2
input the X-axis input for X-Y display.
For X-Y operation the X and Y positions are adjusted using the
CH2 * POSITION X-Y and CH1 * POSITION controls re-
spectively.
X and Y sensitivity is set by using the CH2 and CH
1
VARIABLE,
VOLTS/DIV controls respectively.
By pulling out the two above mentioned POSITION controls,
the sensitivity of both the X and Y axis is magnified by 5 times.
The A INTENSITY control is used to adjust the intensity of the
display during X-Y operation.
[7] SINGLE SWEEP OPERATION
This mode of display is useful for looking at non-synchronous or
one time events.
Procedure:
1.
Set the TRIG MODE to either AUTO or NORM, and the
SLOPE PULL FIX to pushed in position.
Apply a signal of approximately the same amplitude and
frequency as the signal that is to be observed to the CS-
2100A as the trigger signal and set the trigger level.
2.
Set TRIG MODE to SINGLE and press the RESET button
— observe that the green LED lights to indicate the reset
condition.
This LED goes out when the A Sweep period is
completed.
3. After the above set-up is completed the CS-2100A is
ready to operate in the SINGLE sweep mode of operation
after resetting the instrument using the RESET button. In-
put of the trigger signal results in one and only one sweep.
r-CAUTION:
With the HORIZONTAL DISPLAY set to ALT or DUAL, the
simultaneous observation of the A Sweep and B Sweep
waveforms at SINGLE SWEEP mode is not possible. Also
for DUAL or QUAD operation simultaneous observation is
not possible using ALT mode. Set the unit to the CHOP
mode in this case,
[8] DUAL AND QUAD TRACE OPERATION
By setting the MODE to DUAL or QUAD. Dual and Quad trace
operation can be achieved. When necessary, setting
HORIZONTAL DISPLAY to ALT can in addition turn the
CS-2100A into an 8-trace instrument.
Operation of the various controls is for this type of display mode
similar to the operaton described above.
[9] CASCADED OPERATION
This mode of operation is used when sensitivity greater than 1
mV/div is required.
Procedure:
1.
Connect the CH1 output to the CH2 input using a BNC
cable.
2 For cascade operation depress the CH
1
and CH2 x 5 GAIN
switches.
3. Push the CH2 50S2 switch and set V MODE to CH2.
4.
Set the CH
1
and CH2 VOLTS/DIV to 5 mV and input a
sig-
nal for a sensitivity of 500 ^V/div on CH1.
