Output Levels
Maximum +40dBmV, ±3dB (0dB attenuation)
Minimum +10dBmV, ±3dB (30dB attenuation)
Output Attenuator 0 to 30dB in 2dB steps, ±1dB
Bandwidth 300kHz @ –40dB
500kHz @ –50dB
Output Return Loss (75 Ohms) 14dB, 5 to 42MHz
Spurious Outputs –55dBc max. relative to transponder transmit carrier or
–15dBmV max., 5 to 88MHz (referred to a 6MHz measurement
bandwidth)
Low Frequency Disturbances (LFD),
defined as power supply switching
frequency, etc., below band spurious that
may have harmonics to high frequencies.
<–65dBc with transponder installed.
Note: This is different from single in-band spurious requirement
because these spurs are closely spaced.
