Spectrum Analyzer 7L12

The Tektronix 7L12 is a swept-front end spectrum analyzer plug-in for all 7000-Series Oscilloscopes.

CHARACTERISTICS

Frequency Operating Range
100 kHz to 1.8 GHz continuously variable; accuracy ± (10 MHz + 1% of dial indication).

Frequency Span
Calibrated 500 Hz/div to 100 MHz/div within 5% in 1-2-5 sequence. 0 Hz (analyzer, not swept) and maximum span (1.8 GHz) modes are also selectable. Span is continuously variable between steps.

Calibrator
50 MHz ±0.01%  -30 dBm ±0.3 dB. Harmonics of 50 MHz are generated for frequency span calibration.

Reference Level
Selectable -100 dBm to +30 dBm in 10 dBm steps. Continuously variable between steps.

Log Display Mode Dynamic Range
70 dB at 10 dB/div, accuracy 1 dB/10 dB to a maximum of ±1.5 dB over 70 dB range and 14 dB at 2 dB/div, accuracy 0.4 dB/2 dB for a maximum of 1.0 dB over the 14 dB range.

RF Attenuation
0 dB to 60 dB in 10 dB steps ± (0.2 dB or 1% of dB reading, whichever is greater).

Resolution Bandwidth (6 dB down)
300 Hz to 3 MHz in decade steps  ±20%; shape factor: 4:1, 60 dB to 6 dB.

Video Filter Bandwidth
Automatically selected by the resolution control.

CW Sensitivity
-115 dBm at 300 Hz Resolution; -108 dBm at 3 kHz Resolution: -100 dBm at 30 kHz Resolution; -90 dBm at 300 kHz Resolution: -80 dBm at 3 MHz Resolution.

Internal Spurious Responses
Less than -100 dBm, referred to first mixer.

Intermodulation Distortion
Third order: 70 dB down from two -30 dBm signals. Second order: 70 dB down from two -40 dBm signals (within any frequency span).

Incidental FM
Phase locked mode: 200 Hz (P-P) maximum; not phase locked: 20 kHz (P-P) maximum.

Display Flatness
±1.5 dB over any selected span with respect to level at 50 MHz.

Maximum Safe Input Power
RF Attenuation 0 dB: +13 dBm. (-30 dBm linear operating limit) RF Attenuation 60 dB: +30 dBm (Power rating of attenuator).

Sweep Rate
1 µs/div to 10 ms/div in 1-2-5 sequence continuously variable between steps. Variable control has 100:1 range in 10 ms/div position to decrease sweep rate to approximately 1 s/div.

Triggering Modes
Normal, Peak-to-Peak Auto, Single Sweep.

Triggering Sources
Vertical amplifier channels line frequency and free run.
