(b) 3 (as required to remove channel 3 from display).
(c) 4.
(d) [.1] (volts/div).
(e) TRIGGER SOURCE.
(f) [4].
(g) Voltage.
(h) [V p-p].
(35) Set oscilloscope calibrator output for a 50 kHz, 600 mV p-p leveled sinewave
into 50 Ω.
(36) Adjust oscilloscope calibrator output amplitude for a TI indication as close to
600 mV as possible.
(37) Increase oscilloscope calibrator output frequency to 100 MHz (model 54601A) or
to 250 MHz (model 54602A). If TI V p-p indication is not ≥424.8 mV, perform b below.
(38) Set oscilloscope calibrator output to OFF and disconnect equipment setup.
b. Adjustments. Perform Section IV.
11. Time Measurement
a. Performance Check
(1) Connect oscilloscope calibrator to TI channel 1 input using a 50 Ω feedthrough
termination.
(2) Set oscilloscope calibrator for a 1 V p-p, 100 μs time markers into 50 Ω output.
(3) Press TI keys as listed in (a) through (c) below:
(a) Setup.
(b) [Default Setup].
(c) Autoscale.
(4) Set TI Time/div to 20 μs.
(5) Adjust TI Trigger Level to obtain a stable display.
(6) Press TI Time, then press [Freq] and [Period] keys. If TI does not indicate a
frequency between 9.959 kHz and 10.04 kHz and a period between 99.59 μs and 100.4 μs,
perform b below.
(7) Set oscilloscope calibrator output for 1 μs markers.
(8) Set TI Time/div to 200 ns.
(9) Adjust TI Trigger Level to obtain a stable display.
(10) Press TI Time, then press [Freq] and [Period] keys. If TI does not indicate a
frequency between 995.7 kHz and 1.004 MHz and a period between 995.7 ns and 1.004 μs,
perform b below.
