Input Channel Characteristics (continued)
1. AC coupling occurs after 50 Ω termination.
2. When ordered with optional rear terminals, the standard/baseband channel inputs are active on both the front and rear of the universal
counter though the specications provided only apply to the rear terminals. Performance for the front terminals with rear terminals installed
is not specied.
3. Multiply value(s) by 10 for the 50 V range.
4. Stated specication assumes Noise Reject OFF. Noise Reject ON doubles the sensitivity minimum voltage levels.
5. Assumes sine wave.
6. CW only. Assumes AM Rate > 10/gate. For Option 106, spec applies for input powers > -20 dBm; use a tolerance of 15% modulation depth
for frequencies less than 900 MHz. For Option 115, spec applies for input powers > -10 dBm.
