As I know Iran buy Avtobaza ELINT system, not jammers.
The ELINT system displays on the TV screen acquired targets with data on their direction finding, angular coordinates (azimuth and elevation), radiation signal parameters (carrier frequency, duration, pulse repetition frequency) and radar type classification (sidelooking, fire control, low-altitude flight control radar). The APUR automated jamming control system is fed with target data (frequency band number according to frequency assignment of jamming systems, type of emitting radars and their angular coordinates) via cable at a range of up to 100 metres.
Each 1L222 system includes an passive ELINT signals interception system and a jamming module capable of disrupting airborne radars including fire control radars, terrain following radars and ground mapping radars as well as weapon (missile) data links
