To measure a waveform period
To measure a waveform period
Press the (blue) key onthe Entry/Measure keypad.
Press the Period key on the Entry/Measure keypad.
Pressthe 1 key onthe Entry/Measure keypad to select channel number 1.
Notice that Period is shown at the bottom of the display area.
To set the probe attenuation
If you are using a 10 to 1 probe, you may have noticed that the voltage readings you've gotten
are off by a factor of 10. That is because the probe attenuation factor has not yet been set. To
set probe attenuation, use the following procedure.
Press the channel “1 key at the bottom of the vertical area to bring up the
Vertical menu.
Press the more/preset probe softkey at the bottom of the menu.
Note that the probe attenuation field is highlighted and reads 1.000: 1.
Use the knob or numerical keys in the Entry/Measure area to set probe attenuation
to 10.00 : 1.
Notice that as you change the attentuation factor, the voltage measurements at the bottom of
the display change scale also.
To change vertical scale
Press the show key inthe Control area to see the state of the instrument.
Turn the V/div knob, the large knob in the Vertical area of the front panel, and notice
that the signal’s amplitude varies.
Normally, the V/div settings vary in a 1,2,5 sequence. For vernier control of V/div scale, press
the Fine key and then move the V/div knob. Note the lighted indicator next to the key when
the Fine function is in effect.
Turn the small knob, labeled Position (offset), and watch the effect on the signal.
Note the channel numbers between the knobs in the Vertical area, The number that is lit
represents the active channel and that channel is affected by changes made with the knobs.
Also, there are indicators next to each channel key at the bottom of the Vertical area. When a
channel is on, its indicator will be lit.
