3.8 Clear key

While the cursor is within a numeric field, the Clear key erases all digits within the field, allowing the user to start over when entering a value.

This key is also used to select the "Other" mode after the Mode key is pressed once. By selecting Other Mode, a menu of extended modes for the 4070A is presented. See the chapter on Changing Modes.

3.9 MHz/dBm, KHz/Vp-p/Sec, Hz/mVp-p/mS keys

These keys are used to select the units for a numeric value once it has been typed into a parameter field. After entering all digits for a value, you must press one of these keys to complete the entry of the value. In other words, these keys serve as an "enter" key since a value being edited in a cursor field is not accepted and processed until one of these keys is pressed.

After pressing one of these keys, the 4070A will make a double clicking noise to indicate that the value has been accepted. If the entered value is outside the allowable range for the field, the 4070A will give an error beep and set the value to its upper or lower limit.

To enter a value in Volts or milli volts, use the Vp-pand mVp-pkeys, respectively.

When entering a value that has units not listed on the key (i.e. percentage, ohms, etc.), any one of these three keys will work as an enter key.

3.10 One Touch Mode Keys

These keys immediately switch the function generator to the operating mode indicated on the key. These keys make it more convenient to switch to frequently -used operating modes
