Spectrum Analyzer Quick Start

1. Measure the output power of the system being tested, or signal power, at

the system’s test port using a power meter, service monitor, or equivalent.

Note: Ensure the output power is less than +20 dBm (100 mW).

2. Connect the SignalHawk’s “RF Input” connector:

 For low-power applications, connect directly to the output of the sig-

nal source. See the below graph:

 For high-power applications, use a directional coupler or attenuator to

reduce the output level of the signal source. See the below graph:

3. Power up the SignalHawk.

4. In the Start Menu, use the arrow keys to highlight the desired measure-

ment, and press Enter.

5. In the Freq & Span Menu, set the frequency range (See “Freq & Span

Menu” on page 58).

6. Wait for one sweep, then go into the Ampt & Trace Menu and press Auto-

scale (see “Ampt & Trace Menu” on page 70).

CAUTION

Spectrum Analyzer has a +20 dBm (100 mW) max. RF input.

Exceeding the maximum input will damage the SignalHawk.

If unsure of power levels, measure the test connection with

a power sensor before using the SignalHawk.

CAUTION

Center conductor cabling should be discharged prior to connecting.

See “Discharging Static Electricity” on page 131. Any large

electrostatic discharge or high power RF applied directly to the RF

input or output will cause internal damage and void the warranty.

Power to any adjacent broadcast antennas should be shut down

as well. If adjacent antenna broadcasts cannot be terminated,

then adding sufficient external attenuation to the input of the

instrument prior to connecting is recommended. Failure to do so

could result in irreparable damage to the SignalHawk.
