Spetrum Analyser HP141T with 8552A & 8554L 0 - 1250 Mhz

8554L Spectrum Analyzer RF Section 0 - 1250Mhz

Input Impedance: 50 ohm nominal. Reflection coefficient<0.13, input attenuator>=10dB.

Maximum Input Level: peak or average power +13 dBm, +- 50V dc.

Scan Time: 16 internal scan rates from 0.01 ms/div. to 10 sec./div in a 1,2,5 sequence, or manual scan.

Scan Mode:

• INT: Analyzer repetitively scanned by internally generated ramp; synchronization selected by scan trigger.
• SINGLE: Signal scan with reset actuated by front panel pushbutton.
• EXT: scan determined by 0 to +8 volt external signal; scan input impedance >10K,
• BLANKING:-1.5 V external blanking signal required.
• MANUAL: Scan determined by front panel control; continuously variable across CRT in either direction.

Scan Trigger: For Internal Scan Mode, select between:

• AUTO: Scan free runs.
• LINE: scans synchronized with power line frequency.
• EXT: Scan synchronized with>2 volt (20 volt max.) trigger signal
• VIDEO: Scan internally synchronized to envelope of RF input signal

Auxiliary Outputs:

• VERTICAL OUTPUT: Approximately 0 to -0.8 V for 8 division deflectrion on CRT display; parox. 100 ohm output impedance.
• SCAN OUTPUT: Approx. 5 to +5 V for 10 div CRT deflection, 5 k ohm output impedance
• PEN LIFT OUTPUT: 0 TO 14 V, Output available in Int and Single Scan modes and Auto, Line, and Video scan trigger
