• DVM in: 1, 10, 100 and 300V full scale AC or DC. AC
bandwidth 50 Hz to 10 kHz for ±5% F.S. accuracy (AC
dBm calibrated across 600 ohms)
• Frequency counter in: 30 mV or greater required from
10 Hz to 1 MHz. 50 mV or greater required from 1 MHz
to 35 MHz
50 ohms nominal, 125 watts max (1-1000 MHz)
The RF In/Out Jack is protected against RF overload. However,
to prevent undue stress on the protected circuits it is advisable
to always switch the system to the power monitor mode before
applying power in excess of 200 mW. Additional protection is
also obtained by making it a practice not to leave the step
attenuator in the 0 dB position.
Characteristics suitable for Motorola ST-1200 series
