User manual

Proper use

- Measuring and displaying frequencies of 10 Hz min. up to 2500

MHz max. The maximum inputs of 88 Vrms at channel C and of 5

Vpp (peak-to-peak) at channel A and channel B must not be

exceeded. The measurement voltages must be galvanically isola-

ted from the mains (shock hazard).

- Performing measurements under unfavourable ambient conditi-

ons is not permissible. Unfavourable ambient conditions are:

- Moisture or excessive air humidity

- Dust and combustible gases, fumes or solvents

- Thunderstorms or similar conditions such as strong electrosta-

tic fields etc. A use other than the one described above is not

permissible and causes damages to this product. Furthermore,

it involves hazards such as short-circuit, fire, electric shock,

etc.! The entire product must not be changed or modified! The

safety instructions must be adhered to!

Controls

1. BNC-connector for the inputs 1a "A” 50 MHz to 2500 MHz at 1

Mohm, 1b "B” 10 MHz to 500 MHz at 50 ohm, 1c "C” 10 Hz to

10 MHz at 50 ohm

2. Selector switch for adjusting the sensitivity of channel "C”

(High and Low)

3. "RANGE” – selector for range /input switching "CH A” (CH =

channel), "CH B” and for "CH C” the positions "10Hz – 10

MHz” and period (period measurement)

4. Switch "GATE TIME” for adjusting the gate time "FAST” or

"SLOW”
