- 2 - at the center of the 162 sawtooth and delivers 180 ° pulses at the 162 repetition rate as long as S remains open. Unit 161A is triggered by the rising edge of the B output and gates the receiver. 3) T I measurements. Unit 162 runs in "recurrent" mode at a low rate (period more than four times T 1 to be measured). Unit 161B is triggered by return of sawtooth, unit 161C by sawtooth after about 1/5 of period. Unit 161A is again unchanged. Repetition rate is adjusted for zero signal on 90 ° pulse. pulse generators. The following modifications have been made in the a) In unit 161B the leads to the grids of V 5 have been interchanged. The unit now delivers a negative gate rather than a negative pulse (i.e. the output is normally negative and goes to zero during the pulse). Also, the 90 ° pulse delivered by 161C is mixed with the 180 ° pulse of 161B by connecting the cathode of V 4 B in the C-unit to the cathode of V 5 in the B-unit (R 33 of the C-unit is disconnected). b) In o<strong>rd</strong>er to make for easy switching between different operating modes, the trigger circuits of the pulse units have been modified as indicated in Fig. 4. The two trigger modes ("negative sawtooth" and "positive pulse") have been provided with individual input connectors and individual bias potentiometers.
-3- c) The range of all units has been increased by a factor of lO, to provide for very long relaxation times. In unit 162 an additional position with a I0 ~F capacitor has been provided on SW 3. Similarly 1 ~F capacitors have been added to SW 2 of the 161 units.
