Saturation Indicator Impulse Response:
The saturation indicator will properly
indicate saturation for pulsed signals which
fall within the following boundaries:
1. The product of the pulse width to pulse
repetition rate must be greater than .003.
2. The pulse repetition rate must be less
than value listed for the applicable duty
cycle. See the following Table of
Acceptable Pulse Repetition Rates.
5.1.1 Table of Acceptable Pulse Repetition Rates
Duty Cycle Maximum PRF
10 19.7 MHz
20 14.0 MHz
30 9.2 MHz
40 5.6 MHz
50 420.0 kHz
60 130.0 kHz
70 87.0 kHz
80 57.0 kHz
90 30.0 kHz
5.2 Electrical Specifications
Input Impedance:
The input impedance determines the low
frequency roll of point. Depending on the
low frequency roll off selected, the input
impedance is >20 megohms, 1 megohm or
100 kilohm.
Output Impedance: 50 ohm (nominal)
Saturation Impedance:
A red LED on the front panel will illuminate
when the unit begins to saturate or clip. The
saturation indicator will indicate accurately
for any gain and attenuator setting.
Battery Low Indicator:
The power light on the front panel also
serves as a battery low Indicator. If the
green light does not come on when the
power switch is engaged, then the battery
requires recharging. It is recommended that
the Model 3301B be connected to the
battery charger at all times when not in use.
