z User-unit function
Function
Setting items
Coefficient setting
Converts to desired units for set up and display.
Frequency, period, amplitude, DC offset, phase and duty.
Select either [(internal set up) + n] × m, or
[log
10
(internal set up) + n] × m; then, set the value of n and m.
Frequency and period: 15 digits mantissa and 1 digit index (both
m and n)
Amplitude, DC offset, and duty.: 6 digits mantissa and 1 digit
index (m and n)
Phase : 7 digits mantissa and 1 digit index
Unit character string Alphanumeric and 34 symbols
Set up and display up to 4 characters.
z Load function
Function
Load impedance
Range
Resolution
Set up and display at actual voltage for an arbitrary load
Conversion formula:
(Output voltage at load) = (Output voltage at no-load) ×
impedance) (Load+) 50:impedance(Output
impedance) (Load
