HP 4935A Transmission Impairment Measuring Set — Auction Analysis
An HP 4935A transmission impairment measuring set was observed at $10 with one bidder. Seller-reported working condition, unconfirmed option configuration, no demonstrated function, and low-hundreds resale economics leave a $0 standard-reseller ceiling.
Analysis snapshot · Historical — observed August 28, 2026. The scheduled close date of September 3, 2026 has passed. The price, evidence, economics, and recommendation remain exactly as recorded and are not current.

The auction bid ceiling supported by this analysis, if one is defensible; see costs below for buyer-premium treatment.
Why this decision
SKIP: the immutable $10 observed bid is above the $0 standard-reseller ceiling because a $150 conservative resale cannot meet the $500 absolute-profit requirement even before ordinary costs.

Auction snapshot
At the August 28, 2026 open-auction observation, the high bid was $10 with one bidder. It is not a final hammer, award, or settled transaction.
A recognizable legacy test set can have end-user value while still failing a professional reseller's minimum absolute-profit threshold at any positive bid.

How independent review worksHow evidence is classified
Seller facts, photo-derived observations, manufacturer context, unknowns, and LotCaliper assumptions remain explicitly separated.
Photo Derived
Photo-derived
- Supplied photographs establish exterior identity but do not show a powered display or measurement demonstration.
Not Established
Not established
- Current transmitter/receiver accuracy, loopback performance, controls, calibration, battery state, accessories, and option configuration.
- Standard configuration versus Option 001 battery hardware; no option premium is modeled.
Manufacturer Context
Independent context
- Keysight legacy documentation identifies the 4935A as a 20 Hz–110 kHz transmission impairment measuring set and describes option families separately.
- An $8 exact-model completed auction and Best-Offer/asking evidence show a low-hundreds, thin-market context rather than a robust reseller spread.
Lotcaliper Assumption
LotCaliper assumptions
- $150 conservative resale in seller-reported-working but functionally unverified state; conditional tested-working range is not used for the blind decision.
- $0 maximum hammer because the $500 standard profit floor fails before any positive operating cost.

Sensitivity and robustness
Fails
The modeled economics fail the standard reseller requirements under the stated assumptions.
Standard reseller profit-floor model
- Max hammer
- $0
- Gross resale model
- $150
At $150 conservative resale, the $500 minimum-profit requirement alone leaves negative $350 before shipping, testing, selling fees, or uncertainty.
Costs and maximum bid
No cost model is shown because the lot composition and removal scope must be verified before its costs can be modeled.
- Buyer premium
- Not modeled
- Return requirements
- $500 minimum profit · 30% minimum ROI
- Computed bid constraints
Profit floor: $0
ROI floor: $115
Binding: Profit floor
- Snapshot blind/as-is max hammer
- $0
- Modeled result at recorded bid
- No bid recorded
This is a reseller ceiling, not a prediction of the auction's closing price. Any buyer premium or other unquoted acquisition charge must be deducted before bidding.
Legacy telecom function evidence and low-dollar economics
The 4935A is a transmission impairment measuring set, not an RF spectrum analyzer. Seller-reported working is useful but remains weaker than a representative transmitter/receiver test and current calibration evidence.
The $10 observation looks inexpensive, but it does not repair the absolute-dollar economics. A professional reseller cannot recover the required $500 profit from a $150 conservative resale before any handling, testing, selling, or return cost.
- Verify a representative signal path, transmitter output, receiver response, and relevant measurement functions before claiming demonstrated operation.
- Confirm option markings and accessories, but do not assign a battery or option premium without direct evidence.
Recommendation and rationale
Snapshot decision
SKIPSKIP: the immutable $10 observed bid is above the $0 standard-reseller ceiling because a $150 conservative resale cannot meet the $500 absolute-profit requirement even before ordinary costs.

Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
Risks and unknowns
Medium · Seller Reported Function Only
Seller-reported working is not demonstrated by a representative transmitter/receiver measurement.
A lit display would also not establish calibrated measurement performance.
Medium · Option Configuration Unresolved
Standard versus battery-option configuration is unresolved.
No option or battery premium is assigned without direct evidence.
High · Legacy Market Liquidity
Exact-model realized-market evidence is sparse and low-dollar.
The standard $500 profit floor fails before ordinary transaction costs.
