+==Specifications==
+* Markers: 5 s to 1 ns in a 1,2,5 sequence
+* Marker Amplitude: ≥1V peak on 5s through 10 ns; ≥750 mV<sub>p-p</sub> on 5 ns and 2 ns; ≥ 200 mV<sub>p-p</sub>V on 1 ns - All values into 50 Ohm
+*Trigger Output Signal: Slaved to marker output from 5 s through 100 ns . Remains at 100 ns for all faster markers

+* External Reference Input:  1 MHz; 5 MHz; 10 MHz; TTL compatible (Internally hard wired so output frequencies counted down to 1 MHz)
+* Error Readout Range: to ±7,5%
+* Error Readout accuracy: One digit (±0,1%-points)
+* Net Weight: 1 kg
+* Dimensions: 66,8 mm (w/B) x 285,3 mm (d/T) 125,9 mm (h/H)
+==Repair Issues==
+* Check for +15V and adjust if not between 14,3 V and 15,7 V
+* If +5V is not in between 4,94 V and 5,46 V check U626 (LM741 OpAmp). The old OpAmps tend to fail.
+* A lot of ICs are placed in non gold plated IC sockets. Contact problems can occure. Removing and inserting ICs helps.
+* Mounting of A1 board to frame should be done with washers in between, especially near the rear connector. Shorts to conductor tracks can occure otherwise.
