Calibration – Type 1S1
5-21
13. Check Input Dc Resistance
a. Set the resistance bridge for a resistance of 49.00 ohms.
b. Install a GR/BNC plug adapter on the Type 1S1
SIGNAL IN connector.
c. Connect a clip-lead adapter to the GR/BNC adapter
(see Fig. 5-25).
d. Connect the clip leads to the resistance input terminals
of the resistance bridge.
e. Check for an input dc resistance of 49 ohms _±:1 ohm
at the SIGNAL IN connector.
f. Disconnect the clip-leads from the resistance bridge.
g. Remove the connector adapter and clip-lead adapter
from the SIGNAL IN connector.
h. Turn the Type 1S1 right-side up and insert it into the
indicator oscilloscope plug-in compartment.
i. Connect the patch cord from the Type 1S1 HORIZ
OUTPUT jack to the indicator oscilloscope EXT HORIZ Input
jack. (Do not change the horizontal deflection adjustment.)
j. Turn on the indicator oscilloscope and allow about
5 minutes for warm up before continuing the procedure. (If
the Type 1S1 was allowed to cool for very long, let it warm up
for 20 minutes before proceeding.)
Fig. 5-25. Connections for measuring dc input resistance at
SIGNAL IN connector.
k. Secure the Type 1S1 in the indicator oscilloscope with
the securing rod.
