TDS5000B Series Specifications and Performance Verification
H Set the trigger system to trigger on the positive slope of the
waveform before proceeding to the next check.
H Press the Trigger SOURCE button to set the trigger source to CH 1.
H Click Vert in the toolbar. Click Termination 50 Ω. Click Close.
H Disconnect the hookup installed in step 1.
4. Confirm that the trigger system is w ithin sensitivity limits (full bandwidth):
a. Hook up the test-signal source: Connect the signal output of a high-fre-
quency sine wave generator to CH 1 through a precision 50 Ω coaxial
cable. To test some TDS models, a high frequency (>1 GHz) generator is
required; see footnote 1 in Table 2--1 on page 2--19.
b. Set the Horizontal Scale: Set the Horizontal SCALE to 400 ps (500 ps
for TDS5054BE).
c. Display the test signal:
H Set the generator frequency to full bandwidth as follows:
TDS5032B, TDS5034B 350 MHz
TDS5052B, TDS5054B, TDS5054BE 500 MHz
TDS5104B 1 GHz
Note: For the TDS5054BE, set the instrument to E.T. mode.
H Set the test signal amplitude for approximately five divisions
on-screen; then fine-adjust the generator output until the CH 1
Amplitude readout indicates the amplitude is 500 mV. The readout
may fluctuate around 500 mV.
H Disconnect the leveling head at CH 1 and reconnect it to CH 1
through a 5X attenuator. Check that a stable trigger is obtained.
d. Repeat step 2, substeps b and c only, for the full bandwidth selected.
H Press the Trigger SOURCE button to toggle it to CH 1.
e. Display the test signal:
H Set the generator frequency to 100 MHz.
H Set the Horizontal SCALE to 10 ns.
H Remove the 5X attenuator and reconnect the cable to CH 1.
H Set the generator amplitude on the screen for 7.5 divisions.
H Fine-adjust the generator output until the CH 1 Amplitude readout
indicates the amplitude is 750 mV.
