IFDR10 inputs
All IFDR10 inputs are on SMA connectors. The IF signal input is made immediately after the STALO mixing/sideband filtering step of the receiver. The required signal level for both the IF signal and burst is +11.2 dBm for the strongest expected input signal.
You can use a fixed attenuator or IF amplifier to adjust the signal level to be in this range. The maximum signal level is 16 dBm.
| Input | Description |

| IF signals |
IFDR10 has 6 Rx input channels for IF signals: Rx 0 - Rx 5. The user can select which channels are used for primary and secondary polarization IF signals and for wide dynamic range. |

Received over ADC-E. |
| Trigger input or output |
2 trigger outputs on SMA connectors: Trig 0 and Trig 1 ( 50 Ohms / 4 V). 4 trigger inputs in the GPIO panel |
Digitizing is performed for both the IF signal and burst channels from a user-selectable sampling frequency range of 190 ... 240 MHz at 16-bit resolution to sub-nanosecond accuracy. This provides 92 ... 107 dB of dynamic range (depending on pulse width) without using complex AGC, dual A/D ranging, or down-mixing to a lower IF frequency. Each A/D converters is time synced within 1 nanosecond to ensure sampling in multiple channels is of the nearly equivalent targets.
RVP10 provides AFC support for tuning the STALO of a magnetron system. Alternatively, the magnetron can be tuned by a motorized tuning circuit controlled by RVP10.
