PERFORMANCE TEST
4 - 47
Test setup:
1
-
Press the ANALOG key (’DIGITAL MODE’ is displayed briefly) to activate
the digital mode.
2
-
Apply a 100 MHz sine-wave signal of 1 V(pp into 50 ohm) from the
constant amplitude sine-wave generator to input CH1.
3
-
Press the AUTOSET key, and set CH1 to 0.5V/division.
4
-
Use a 50 ohm termination. For instruments with switchable 50 ohm input
impedance it is recommended to make use of this feature (via
VERT MENU key).
5
-
Set the input coupling to DC and POSition the signal in the vertical center
of the screen.
6
-
Select 5.00 ns/division for MAIN TB.
7
-
Press the TRIGGER menu key and select ’logic’, ’pattern’, and ’enter’ from
the related menu.
8
-
Operate the front panel keys TRIG1, TRIG2, TRIG3 and TRIG4 to obtain
the trigger pattern Hxxx (x = don’t care) in the menu.
9
-
Press the TB MODE menu key and select ’trig’ from the related menu.
10 -
Decrease the amplitude of the generator voltage to 1 division.
11 -
Turn the TRIGGER LEVEL control and check that a well-triggered signal
is obtained.
12 -
Apply a 300 MHz sine-wave signal of 2 V(pp into 50
Ω
) from the SG 504 to
input CH1.
13 -
Adjust the input voltage to 2 divisions.
14 -
Verify that the signal is well triggered at amplitudes of 2 divisions and
more; adjust TRIGGER LEVEL when necessary.
15 -
Press the ANALOG key (’ANALOG MODE’ is displayed briefly) to return
to analog mode.
Repeat the procedure for CH2 with trigger pattern xHxx
Repeat the procedure for CH3 with trigger pattern xxHx
Repeat the procedure for CH4 with trigger pattern xxxH
