TTL/CMOS Output
Press SHIFT + 9 (TTL) keys, a TTL compatible waveform
will be obtained from the output by pushing back and rotating the
TTL/CMOS knob
⑰
, and a CMOS compatible waveform (5Vp-p
to 15Vp-p) will be obtained from the output while the TTL/CMOS
knob is pulled out and rotated.
⑮
Output Amplitude Control with Attenuation operation
Turn the knob clockwise for increasing output level and invert for
decreasing. Pull the knob out for an additional 20dB output
attenuation. This attenuation will not change the LED status.
⑯
DC Offset Control
Pull out the knob to turn the DC offset of the waveform
between –5V to +5V (into 50
Ω
load), turn the knob clockwise to
set a positive going DC level waveform and turn reversely for a
negative going DC level waveform.
⑰
TTL/CMOS Selector
When the TTL/CMOS output is turn on, push back this knob to
select the TTL as the output and pull out this knob to select
CMOS. When the CMOS is selected, rotate the knob to set the
CMOS level.
