PSK, ASK, OSK modulating modes, frequency sweep, list sweep and burst modes. Also
can output internal trigger signal under frequency sweep, list sweep, burst output mode.
5.19 Communication Port
5.19.1 USB Host
This connector is provided on front panel, which is used to insert U-disk to store and
recall the user-defined waveforms or instrument state, or used for system update.
5.19.2 USB Device
The USB Device connector is provided on rear panel, which be connected with PC using
USB cable to remote control the instrument, or download the user-defined waveform with
waveform edit software, or update the instrument using firmware updating software. For
detail instruction, please refer to CD.
5.19.3 LAN Port
The LAN Port is provided on rear panel, which be connected with PC to remote control
for the instrument. For detail instruction, please refer to CD.
5.20 Calibration
The waveform generator is secured when shipped from factory. After a long time
operating, some parameters are possible have a change. To guarantee the accuracy,
periodical calibration is needed. It’s no necessary to open case for calibration but just
using keypad.
Professional staffs are required for calibration work and calibration used instruments
must comply with the accuracy requirements. When calibrating, the instrument needs to
be warmed up more than 30 minutes and the environments should be meet the
specification required.
When power off, the generator will automatically recall the calibration code stored on last
time. Turning off the calibration is used to prevent the calibration code to be modified.
5.20.1 Enable Calibration
Press 【Utility】key then to 〖Calibrate〗softkey.
Press〖Password〗key then enter calibration code. Press〖Finish〗to enter into calibration
window. User can make calibration to frequency, offset, amplitude, flatness, offset level
and trigger level of counter, the relationship among offset, amplitude and flatness
separately by knob, numeric keys and Last Page/Next Page.
