The unit will display the output level parameter as shown in Figure 6, 7 seconds after the last change on the second line of LCD display.
External voltage control generator.
The current output frequency should be changed to 878 KHz by controlling the DC level applied to VCG/SWEEP input jack. Apply a
DC level b 5.0 V and + 10.0 V. The output frequency must sweep a range between 17.56 KHz and 8.78 KHz.
Illustrated below shows what will happen at the limits of the DC level range applied to the
VCG/SWEEP
jack.
Step 9
Apply a + 5.0 V DC level at the
VCG/SWEEP
jack. The output frequency will be
17.56 KHz, and the LCD display should look like Figure 9 at the start of the
frequency sweep.
Step 10
Change the DC level until it r 10.0V. The output frequency will reach 8.78
KHz, and the LCD display should look like Figure 10 at the end of the frequency
sweep.
3.2.5.2 Example of setting parameters in INTERNAL SWEEP mode.
To output a square wave signal whose frequency sweeps a 6MHz range in 21.33s, set the sweep frequency to start at 8.000MHz,
symmetry 40%, level 500mV

, DC 2.10V. Set a CMOS output level to + 4.0 V (unloaded).
Step 1
Press the
UP
button 3 times to reach the desired frequency range (see Table1). The
LCD display should look like Figure 11. The output frequency will now be 2.2222
MHz.
Step 2
Turn the
FREQUENCY
knob clockwise until you reach the desired frequency,
8.000MHz. The LCD display should look like Figure 12. The output frequency is
now 8.0 MHz.
