MF-MD マルチ復調オプション
マルチ復調オプションは、MFLIに拡張できます。
- 3つの追加復調器、合計４つ。
- 3つの追加発振器、合計４つ。
- 1つの追加外部参照PLL、合計２つ。
例えば、４つのプローブ計測や最大４周波数のデータを同時に信号から抽出できます。各復調器の入力とフィルタは、完全に独立しています。
In combination with the MFLI instrument, these upgrades enable simultaneous measurement of the current input and the voltage inputs, as required for a number of applications. Moreover, data for up to 4 arbitrary frequencies – including higher harmonics – can be extracted from a signal at the same time. Each demodulator's input and filter settings can be set entirely independent.
In combination with the MF-IA option or the MFIA instrument, this option adds a second impedance measurement unit to the instrument and allows the user to probe their DUT at 2 frequencies simultaneously. Whenever measurements at multiple frequencies have to be done on a regular basis, this feature can help to simplify the setup and speed up measurements by up to a factor of 2.
The following table gives a quick overview of the main features affected by the MF-MD option and the MF-IA option.
| Features | MFLI | MFIA, MFLI +MF-IA |
MFLI + MF-MD | MFIA + MF-MD |
| Simultaneous demodulation of current input and voltage input |
- | ✓ | ✓ | ✓ |
| Number of oscillators | 1 | 1 | 4 | 4 |
| Number of demodulators | 1 | 2 | 4 | 4 |
| Number of impedance units | 0 | 1 | 0 | 2 |
| Number of external references | 1 | 1 | 2 | 2 |
The listed features are independent of the frequency range and other options installed on the instrument.
