Error Messages
Frequency
error
Err-1
Sine, square, and TTL wave frequency over
range. This message appears when entering
sine / square / TTL waveform frequency
larger than 3MHz. The frequency is
automatically forced to 3MHz.
Err-2
Triangle wave Frequency over range. This
message appears when entering triangle
waveform frequency larger than 1MHz. The
frequency is automatically forced to 1MHz.
Err-4
Frequency over resolution. This message
appears when trying to enter frequency less
than 0.1Hz. The frequency is automatically
forced to 0.1 Hz.
