Changing the frequency using the up / down keys
SPM-32A/-33A/-34A/-36A:
• The repeat function comes into effect if you hold down
any of the up / down keys. The step width for keys
marked with one arrow is increased to 10 Hz when a
bandwidth
>25 (100) Hz is selected.
• When TUNE mode has been selected, the up / down
keys are a good way of fine tuning the instrument.
