When you're putting together an RF network, cable, or telecom test bench, the first fork in the road isn't budget-it's the kind of measurement you need. A directional bridge and an RF power meter solve different problems. The HP 85020A Directional Bridge is a used directional bridge; the V7.0 RF Power Meter is an RF power meter. Both can earn a spot on a test bench, but they serve different jobs. Here's how to choose between them.
Quick Verdict
If your next project involves bench RF work, the HP 85020A gives you a directional bridge package. If you want a portable power meter and a lower listed price, the V7.0 RF Power Meter is the more direct fit.
At a Glance
| Product | Listed price | Condition | What it does | Price bar |
|---|---|---|---|---|
| HP 85020A Directional Bridge | USD 500.00 | Used | 10 MHz-4.3 GHz directional bridge for RF measurements, signal testing, and microwave applications; includes attached cable and carry/storage case | |
| V7.0 RF Power Meter | USD 155.54 | New | 10 GHz RF power meter for amp gain measurement; Type-C powered with built-in digitally programmable attenuator |
Where Each Product Wins
Where the HP 85020A wins
You'd pick the HP 85020A when you need a directional bridge rather than a power meter. It's a used unit from HP's test equipment line, and it's ready for bench RF work. The trade-off is its used, as-is condition, so you have to accept some cleanup and prep before it becomes a daily driver.
Where the V7.0 RF Power Meter wins
The V7.0 RF Power Meter is the pick if you want an RF power meter with a computer-configurable workflow. It's compact and described as easy to use, with stable performance and a wide dynamic range. The software-based data sharing makes it a solid fit for repetitive gain checks.
Product Notes
HP 85020A Directional Bridge
The HP 85020A Directional Bridge is a used directional bridge covering 10 MHz to 4.3 GHz. It includes the bridge unit, an attached cable, and a carry/storage case, which makes it a complete starting point for RF measurements, signal testing, and microwave applications. Choose this one if you want a directional bridge with the accessories included and you're comfortable with an as-is instrument. The limitation is the used condition: the foam inside the case has deteriorated due to age and may need to be replaced or cleaned. That's not a deal-breaker for a bench tool, but it is real prep work to factor in.
V7.0 RF Power Meter
The V7.0 RF Power Meter is a new instrument for RF power measurement and amp gain testing up to 10GHz. The Type-C interface handles both power and data communication, and the companion software lets you configure the meter from a computer and record or share measurement data. It also includes a built-in digitally programmable attenuator, which is useful when you need repeatable gain measurements across a wide dynamic range. For most portable RF power jobs, the V7.0 is the better fit if you want a lower listed price than a used directional bridge. It's a power meter rather than a directional bridge, so you'll need separate gear for tasks that only a bridge can handle.
Final Choice by Use Case
- For bench RF work, the HP 85020A Directional Bridge at USD 500 is the one to choose when you need a directional bridge and can accept a used unit with aged foam.
- For RF power readings, the V7.0 RF Power Meter at USD 155.54 is the more practical pick if you want a lower entry cost.
