the 3 revitions of this model was released 1987-1989
this one is with tracking generator, battery charger, external DC input,
quite nice with the 10kHz to 2600MHz range, input can be as high at +30dBm with max attenuation, two Z80 CPU one for the main software and one for the screen, all software is stored in UV-EPROM's
i bend a wire from a tantalium, maybe it was shorted, and removed zero volts lithium cell, now it runs and measure quite fine, ok readout a few dB too much. maybe i just need to figure out the calibration routines, and put in a new 3V cell.
