DC - 470 MHz, 4-CH, 10 traces |
Four channels up to 470 MHz are available, with CH1 and CH2 boasting the widest frequency range with highest sensitivity (2mV/div). The fastest sweep speed is 500 ps/div. |
Input offset function |
Suitable for the observation of small signals superimposed on large signals. The DC input offset function features an offset equivalent to ±500 div. max, which can be applied to CH1 or CH2. |
Counter measurement function |
Built-in 5 digit counter for frequencies up to 470 MHz. |
Save/Recall up to 256 panel settings |
Just turn the FUNCTION knob to recall panel setups. Stores up to 256 settings in memory. |
Power for FET Probe |
Dedicated power supplies for 2 FET probes. Controls DC offset voltage of each probe as well. |
TV/HDTV Synchronization |
TV triggering is available for NTSC, PAL, (SECAM) and HDTV. Field (EVEN, ODD, BOTH) and line select functions are included. |
TV Clamp Function |
Easy observation of TV video signals with fluctuating average voltage. Back porch level of composite signals is fixed to ground level for display. |
