Setting up Measurement Conditions and Display
Setting Up Measurement Signals (Frequency And Level)
To set up the signal level compensation feature:
Step 1. Press [Meas Setup].
Step 2. Use the cursor keys to select the LVL COMP field.
Step 3. Use the following softkeys:
Level error of the signal level compensation function
Even if you use the signal level compensation function, signal level drop occurs
at larger capacitance with larger D (refer to “Signal Level Compensation (SLC)
function” on page 193).
The status in which capacity further increases and the output current of the
signal source approaches the limit (approximately 1 Arms) is judged as
overload. In this case, OVLD appears on the display.
Executing signal level check
When level error becomes over 10%. If the applied signal level for DUT is
dropped more than 10% from the setting level the following error occurs:
• When both SLC and contact check are ON, generates contact check error.
• When SLC is ON and contact check is OFF, generates OVLD (overload)
error.
For more information on contact check, refer to “Setting up Contact Check” on
page 66.
Softkey Description
ON Turns ON the signal level compensation feature.
OFF Turns OFF the signal level compensation feature.
In E4981A, the AC level monitor is always ON.
