Keyboard Introduction - PeakTech 4055 MV Bedienungsanleitung

2.4. Keyboard introduction

There are totally 28 keys on the front panel (see front panel picture), the functions of which respectively are:
* 【0】【1】【2】【3】【4】【5】【6】【7】【8】【9】keys: Digits inputting key.
* 【.】key: Point inputting key.
* 【-】key: Minus inputting key, press this key to input minus under "offset" option. Press this key to
enable or disable the key-tone circularly under other options.
* 【＜】key: Move the cursor left; delete the input when inputting digits.
* 【＞】key: Move the cursor right.
* 【Freq】【Period】key: select frequency and period circularly, disable calibration process when
calibrating.
* 【Ampl】【Atten】key: select amplitude and attenuation circularly.
* 【Offset】key: select offset.
* 【FM】【AM】【PM】【PWM】【FSK】【Sweep】【Burst】key: respectively select and exit FM, AM,
PM, PWM, FSK, frequency sweeping and burst function.
* 【Trigg】key: select external trigger under frequency sweeping, FSK modulation and burst function.
* 【Output】key: open and close output signal circularly.
* 【Shift】key: select shift key, return back to keyboard function under remote control state.
* 【Sine】【Square】【Ramp】key: shift key, select respectively sinewave, square and ramp three
common waveforms.
* 【Arb】key: shift key, select 16 kinds of waveforms with the waveforms sequence number.
* 【Duty】key: shift key, select duty cycle of square and symmetry of ramp.
* 【Cal】key: shift key, select parameter calibration function.
* Unit key: The six keys with unit characters above them on the bottom of the instrument are not shift
keys, but double-function keys, press these keys directly to execute the functions marked on
themselves; when inputting digits with numeric keys, press these six keys to select the unit of the
inputting and end the digits Inputting at the same time.
* 【Menu】key: key for menu, select different options circularly under different functions, see below list:
