Description
• 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
10Hz to 1 MHz. 50 mV or greater required from 1 MHz
to 35 MHz
50 ohms nominal, 125 watts max (1-1000 MHz)
CAUTION:
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
Wattmeter Elements
70 to 350 mV rms input required at 10 MHz,
impedance greater than 50 ohms.
Output
Up to 11 vpp into 600 ohms 10 Hz to 10 kHz
Typically 3 vpp into 600 ohms for ±5 kHz deviation
narrowband, 4 vpp for ±75kHz deviation wideband,
DC to 10 kHz response
1.0 Vrms (+13 dBm} to 0.1 Vrms (-127 dBm) 50 ohm
nominal source impedance. 10kHz to 1.0 GHz.
-30 dBm typical, 50 ohm nominal source impedance
2 MHz to 1 GHz
250 mV rms nominal output into 50 ohms
