Quick start EN External storage device (USB disk) can be accessed for saving or loading settings files. The file system format of the external storage device is FAT32 and the memory is no more than 32G. 4.4.2 Rear Panel Figure 4.4 Rear Panel 1. CH1/CH2 Sync/ExtMod/Trig Connector BNC connector with 50Ω nominal output impedance and 1KΩ nominal input impedance. Its function is determined by the current working mode. ⚫ Sync:When 1Output is enabled, this connector outputs the sync signal corresponding to the current settings of CH1 (refer to the introduction in Sync ). ⚫ ExtMod:
If modulation mode is enabled for CH1, and external modulation source is used, this connector accepts an external modulation signal. ⚫ Trig: If CH1 is in sweep or burst mode and external trigger source is used, this connector accepts an external trigger signal (the polarity of the signal can be set). 2. CH3 SYNC Output Connector BNC connector with 50Ω nominal output impedance. When CH3 output is turned on, the connector outputs the sync signal corresponding to the current settings of CH3 (refer to the introduction in Sync ). 3. CH3 Output Connector BNC connector with 50Ω nominal output impedance.
When CH3 output is turned on (press [CH1/2/3] to select the CH3 window display, then press CH3 softkey and switch to "ON"), the corresponding connector outputs the configured waveform. HDG3000C User manual Copyright © Qingdao Hantek Electronics Co., LTD 14
