A step up from the HF35C in both frequency range (700MHz-3.3GHz vs. 800MHz-2.7GHz) and sensitivity -- the manufacturer states it's roughly 10 times more sensitive than the HF35C and 100 times more sensitive than their entry-level HF32D. Adds a Peak Hold setting alongside Peak and Average, useful for catching short, strong RF bursts such as those from smart meters.
What to check
Accuracy/linearity deviation is manufacturer-specified at +/-6dB. Maximum display resolution requires the external DG20 attenuator (sold separately) to read very strong signals.
Confirm the exact model revision and the measurement conditions that matter to your use. Detection coverage is not a guarantee of uniform accuracy.
