Overview
The Picotest J2120A Line Injector allows the input DC supply voltage to be modulated by the network analyzer source signal, as in the case of a PSRR measurement. The line injector must be capable of a frequency range well below the AC line frequency and at least above the control loop bandwidth of the circuit being tested.Characteristic | Typical | Units | |
Maximum DC Input Voltage | 50 | VDC | |
Maximum Continuous Current | 5 | A | |
Maximum Voltage Drop | 3.25 |

Modulation Input Impedance | 10K | ohms | |
3dB Frequency Response | 15-5M | Hz | |
Useable Frequency Response | 10-10M | Hz | |
Recommended Injection Signal | -20 - 0 | dBm | |
Temperature Range | 0-50 | C | |
Maximum Altitude | 6000 | Ft | |
Absolute Maximum Voltage | < 50V (DC + AC) |
J2120A is the lowest impedance injector on the market and can be approximated by the following relationship to operating current.
Or about 180mOhms at 1Amp
Caution: To avoid equipment damage and/or severe injuries or death ensure that the absolute maximum ratings are observed and not exceeded at all times.
EMI Note: Exceeding 0dBm may cause the unit to exceed CE EMI limits.
