Calibration-7D15
e . Set the 7D15 MODEto PERIODA, the AVERG
switches to 1000, and the CLOCKto 10 ns.
f. Check that the 7D15 can be triggered and the
displayed readout is10 ns.
g . Disconnect alltestequipment .

Fig.5-4 . Equipmentsetup used to check TIM A+13 accuracy .a . Remove the 7D15 Plug-In from the Flexible Ex-
tender and plug itdirectlyintothe A Horizontal compart-
ment of the oscilloscope mainframe .Set the Channel A
and B P-P SENS controls to TRIG SOURCE.
NOTE
b . Connect a 100 MHz sine wave from the Sine-Wave
Use the VerticalPlug-In unit to set the outputGenerator to the VerticalPlug-Inthrough a Feed-Through
amplitude of the Sine-Wave Generator .Termination and obtain a crtdisplay of 0 .5division.
c . Check thatthe 7D15 can be triggered and that the
,,/13. INPUT TRIGGERSENSITIVITY (CHECK)displayed readout isapproximately 10 ns.
a . Connect a 225 MHz, 150 mV peak-to-peak signal
from the Sine-Wave Generator to the 7D15 B FREQ IN
connector through a Feed-Through Termination .d . Change the Sine-Wave Generator frequency to
225 MHz and obtain a crtdisplay of 0.5division.
b . Set the 7D15 MODEswitch to FREQ B, the TIME
switches to 10 ms and SOURCEto INPUT B .e . Change the 7D15 MODE to FREQ Band theTIME to
10 ms .
c . Check that the 7D15 can be triggered and thatthe
displayed readout is225 MHz .f. Check that the 7D15 can be triggered and thatthe
displayed readout isapproximately 225 MHz .
d . Change the Sine-Wave Generator frequency to
100 MHz and move the output to the A input.g . Disconnect alltestequipment . |
